Acheron, the Dark Wizard, also known as the Magic Thief and posthumously the Vengeful Darkness, is the main antagonist of the 2015 Roblox game Arcane Adventures.
Once a young boy without any magical ability, Acheron came across the Absorption Sea Curse. Realising his true potential during a bandit raid on his village, he sought to steal all the magic in the world and someday rule it, his conquest claiming the lives of thousands if not millions of innocent lives and completely reshaping the world. He was the archenemy of Theos, the War Phoenix and the nemesis of the Peacekeeper.
Appearance[]
Acheron's human form has never been shown, so there is almost nothing known about his appearance before he transformed into a spirit. The only known thing is that he had curly black hair as a kid, as stated in Arcane Chronicles.
As a spirit, Acheron only consists of two layers, one purple in the middle and one black around it. He also constantly emits a purple, smoke-like aura around him.
In his initial design for Arcane Adventures, Acheron consisted of an all-black humanoid figure, again emitting a smoke-like black aura around him, as well as having seals of all types of magic bound together by some sort of magic surrounding his head, all connected to the Shadow magic just above his head.
Personality[]
Acheron's early years were marked by isolation. Unlike the majority of children around him, he possessed no magical ability. In a world where magic was not only common but central to identity and status, this absence left him feeling disconnected. His inability to relate to others made him distant and quiet. He rarely sought interaction and preferred to remain alone, living a calm and uneventful life. At that time, Acheron showed no signs of aggression or malice; he had no interest in conflict and never sought to harm anyone.
However, this quiet existence changed drastically after his encounter with Hades, the god of the Underworld. It was this meeting that awakened a dormant potential within him; a force previously inaccessible, tied not to ordinary magic, but to dark and forbidden powers. From that moment on, Acheron began to immerse himself in magical knowledge, particularly in sea curses and necromancy. What began as a newfound passion soon turned into an obsession. He no longer simply wished to understand magic, he wanted to own it. He resolved to take all magic for himself, regardless of who it belonged to or the consequences of doing so.
As his goals evolved, so too did his personality. Acheron's sense of morality faded completely. The difference between right and wrong became irrelevant to him, and ethical boundaries meant nothing. His actions were driven entirely by ambition and self-interest. He adopted the title of the "Magic Thief", not as an insult, but as a declaration of intent. He would steal, corrupt, and consume any magical force he encountered to fuel his rise. The idea of world domination was no longer far-fetched to him, it became a stepping stone toward his ultimate purpose: total magical supremacy.
Over the years, Acheron grew increasingly ruthless and arrogant. What traces of restraint or empathy he may have once had were lost. He developed a cold and vindictive nature, holding long-lasting grudges and eliminating anyone who dared to oppose him. By this point, the destruction he caused was not accidental, it was simply collateral damage he chose to ignore. In a devastating battle against Theos, Acheron’s actions led to the near-complete destruction, 80% of the world to be exact. However, to him, the scale of destruction was meaningless, and his only regret was that Theos had survived. His obsession with eliminating this rival overshadowed any concern for the devastation left in his wake.
In addition, despite his immense power, Acheron often avoids direct combat. He prefers to remain in the background, pulling the strings while letting his undead armies and cursed minions fight on his behalf. He rarely shows himself unless absolutely necessary. This is not out of fear, but because he sees himself as too important to be exposed to danger. His armies, which he can rebuild at will, are expendable tools. In his view, their only purpose is to delay or weaken the enemy. This detached and superior attitude, however, often leads him to underestimate his opponents. He sees them as beneath him, and this arrogance frequently results in his forces being defeated without accomplishing anything significant.
Acheron also seems to have a personality that can easily lose its cool, especially if things don't go according to his plans, and he can make sudden and unthinking decisions because he wants everything to go well and to ensure his victory. For example, as if Prometheus wasn't enough, he also resurrected Zeus and threw everything he had at the One-Shot Pirates. Although it worked for him in the short term, this reckless action left him with nothing when he faced the Peacekeeper, and ultimately resulted in his defeat.
Even after acquiring godlike powers, Acheron was never able to overcome one crucial weakness: his fear of failure. No matter how powerful he was, he remained afraid of being defeated and having his plans thwarted by someone else, only to see them achieve "victory" through him. His entire life had been built on proving his worth and gaining absolute control, and the thought of his plans being ruined by someone else was unbearable, intolerable to him. This fear was so deep that in the end, Acheron chose to destroy himself rather than allow his defeat to be attributed to someone else. If his end were inevitable, it would not be the result of someone else's victory, but by his own hand.
Biography[]
Becoming the Magic Thief[]
As a young boy, Acheron was born with no magical ability at all, feeling distant from the other children in his village as a result. During a walk through a forest, he came across a large purple cube. Putting his hand through it, the cube exploded in a flash of light. He felt extremely powerful, but had no idea what had happened, and returned to his village the same day. Not too long after, bandits attacked the village using magic. His house collapsed on him while he slept, breaking his left arm. Seeing the bandit that had destroyed his house, he felt compelled by some force, secretly the god Hades, to raise his right arm, draining the man of his magic energy, killing him. Acheron could now summon the magic circles required to cast Light Magic, realising the cube he had encountered was the Absorption Curse, and he now had its power.
Travelling the world for three years, Acheron became known as the Magic Thief, able to use all seven types of known magic: Fire, Lightning, Light, Wind, Earth, Water, and Shadow. During his exploits, a man challenged him to a fight. Acheron accepted, baffled when the man started laughing after converting his own arm to dirt, even more baffled when he couldn't absorb his magic, the man having no magic energy whatsoever. The man told him had never been magical before, to which Acheron realised he was a fellow curse user, the Earth Curse. Acheron switched tactics, instead draining his physical energy, tiring him out. Acheron then killed the man and stole his Sea Curse.
After gaining many Curses, he used their powers to build a tower, which he would stay in for the next decade. He experiment with his abilities, learning how to revive the dead, reverse the effects of Curses, combine them and even turn a magic into a more powerful form of itself, which later came to be known as Mutating. The world advances around him as he remains in his tower, with there being around thirty different types of magic, borne of Mutations. Despite his prior knowledge of them, his lack of innate magic ability meant he had to wait for the outside world to discover and start using them so he could steal them. Not wanting his research to be interrupted, he resisted the urge to emerge into the world once more, remaining in his tower. Having remained in hiding for so long, the world forgets about him.
Encounter with Theos the War Phoenix[]
Four years later, Acheron leaves his tower and returns to his old ways, feeling his lust for power return after stealing Sun Magic and Flash Magic. He came to the city of Oberon, the largest city in the world at the time, setting his sights on the gatekeeper, Theos the Phoenix's, magic. Theos proves too powerful for him to absorb his magic easily and the duo duel for hours, eventually destroying the city's gate. Theos is forced to retreat into the city, but Acheron is shaken by the encounter, retreating as well. He decides to build an undead army to help defeat him.
Another four years later, he completes his army of undead peasants and mages. He provides some of them with magic. Will they march to Oberon, he gains the powers of the Lightning and Explosion Curses.
The army reaches Oberon by the beginning of the next year, only for it to easily by wiped out by Theos. Now locked in a one on one dual once more, Acheron found himself close to death, having lost his right leg in the clash. In a last desperate attempt to save his life, he combined all his power into a single blast. It missed Theos, instead hitting a mountain behind him, causing an explosion so great it reduced eighty percent of the human race to ash, irreversibly altering the world at the same time. It filled the skies and sea with magic pollution causing massive tsunamis, huge storms, snow in deserts, and other various weather anomalies. Some areas of the earth became so malicious and polluted with energy that life could no longer existed there. The energy in the atmosphere and seas would remain this way for about five hundred years, until it finally dissipated into space, which returned the world's weather back to normal. However, one effect that never changed was how Sea Curses interacted with the water. The pollution now meant Curse users could no longer swim in the world's oceans, which now encompassed far more of the world than they had before.
The New World[]
Three hundred years later, Theos, now referred to as the War Phoenix, hunted Acheron across the Seven Seas for the destruction of his home and family. Meanwhile, Acheron was rebuilding his undead army, ensuring to always stay a sea away from Theos. However, in the wake of the destruction he had caused, the Seven Seas now had a central government, the Arcane Government. He viewed them more as a nuisance than a threat. Most of the commanders were Curse users, meaning that he needed to engage in long prolonged fights with them to steal their Curses, during which they could easily call for reinforcements and overwhelm him. In retaliation, he used his necromancy to resurrect some of their fallen ships, making them unsinkable. Knowing he couldn't risk getting captured and with encouragement from Hades, he shed his body and went into hiding, now an immortal dark spirit.
Hoping to obtain influence in the First Sea, he broke the minds of promising mages there and murdered Ramses II, ruler of Savaria, as well as large swathes of its population. Three years later, he returned to Savaria, resurrecting his victims. However, the spell had gone wrong, and he would inadvertently resurrect one of the victims of his attack that had taken the life of eighty percent of the world's population, a person would prove to be his greatest foe, the Peacekeeper, granting the once magicless peasant some of the greatest potential of any mage.
They materialised near Theos in Newground Island, where they helped him kill the wizard's who had been driven to madness by Acheron. During their travels, the Peacekeeper was able to lay Ramses II and his forces to rest once more, ending Acheron's influence in the First Sea. They later encountered Theos again in the Second Sea, who revealed to them his history with Acheron and how he was responsible for most of the evil in the world, recruiting them in his quest to kill the dark wizard once and for all. During this time, Arthur the Cursebeard, captain of the One-Shot Pirates, began to see the threat Acheron presented, sailing to the Seventh Sea to kill him. Fearful of the man who had killed the very gods, Acheron resorted to a secret weapon, he resurrected Prometheus, the very progenitor of magic itself.
Becoming aware of Theos in Stormwall Island, Acheron travelled there with Prometheus, seeking to kill his rival once and for all. The fight is interrupted by the Peacekeeper, who helps Theos kill Prometheus once more, but Theos loses his life in the process. In his dying breath, he requests they end Acheron for good.
Defeat and Death[]
The One-Shot Pirates finally came face to face with Acheron's army, resulting in a naval battle that riddled the sea with thunderstorms, cannon fire, tsunamis and enormous icebergs. Out of desperation, Acheron revived Zeus as well. Acheron's forces began to slowly win the fight, converting every pirate they killed into another undead soldier, soon only Arthur and one of his officers, Poseidon, God of the Sea, remained. By the time Peacekeeper arrived in the Seventh Sea, Arthur was dying, while Poseidon fought his undead brother, eventually being killed by him, allowing Acheron to revive him. Arthur and Poseidon duelled fiercely, the seas around them forming enormous waves that stood still in the air due to the two’s abilities to control the ocean, while the ground shook with the strength of an earthquake due to their power. Arthur had to use his full power to kill Poseidon, something he hadn’t needed to do since he had raided and destroyed Mount Olympus. Ambushed by Zeus, Arthur finally gave in from it all and was killed.
With only Peacekeeper left, Acheron sought to finish off the only remaining threat to his power. In the fight that followed, Zeus was killed and Acheron was defeated. Desperately trying to do anything to escape, Acheron blew himself up in a final suicide attack, killing himself, freeing all his previously absorbed Curses but also destroyed the Fourth, Fifth and Seventh Seas, and sent a large portion of the earth's curst into space.
Legacy[]
The effects of his blast were felt for a few months all around the world, causing tsunamis, earthquakes, and more insane weather. In the War Seas, this event became known as “The Wrath of the Gods.” Tales of the one who had finally slain Acheron spread far and wide, and they became known as “The Peacekeeper.” Chaos energy was attracted to the world by the cataclysm, and it ravaged the four remaining seas, entirely wiping entire islands off the map. The destruction of the Fifth Sea also lead to the end of the Arcane Government, as their headquarters and most of their high ranking members were located there. The intense magic radiation that infested the seas mutated sea life, making some unnaturally large and giving birth to the infamous Poison Jaws and White Eyes.
The story of his battles with Theos also spawned a religion. Followers of this religion saw Theos as a religious figure, known as the Great Protector, while Acheron was named the Vengeful Darkness. This grew to be one of the most prolific religions in the War Seas.
Three years later Hades was discovered by the Peacekeeper, revealing himself to be the one who had helped Acheron in his fall, hoping to use him to test the limits of pure dark magic. The two fought and Hades was killed, removing the last major threat from the old world, and killing the last of the Greek Pantheon. Learning from this the way to destroy Sea Curses, they set out and found the Absorption Curse, planning to use it to destroy the Sea Curses once and for all.
Relationships[]
Hades, the Revolting[]
Despite being the direct cause of Acheron's transformation into a dark entity and later the Magic Thief, Hades had no apparent relationship with Acheron. Throughout the story, he has merely entered his mind and given him instructions, especially when he first discovered the Absorption Magic; encouraging him to follow the dark path. However, it was never revealed whether Acheron knew that it was Hades speaking to him in his mind. It is unknown whether he saw it as a voice inside him or if he was aware that someone else was speaking to him. In the most realistic scenario, Acheron was aware that the voice in his mind belonged to someone else and was manipulating him, but he chose to listen to it of his own free will, without knowing the fact that it was none other than the God of Underworld himself.
Theos, the War Phoenix[]
Acheron and Theos are clear archenemies, with a long and bitter history between them. As the Phoenix user he once fought, Acheron inflicted deep personal losses, twice invading Theos’ homeland and causing the deaths of those close to him during a devastating final assault. This left Theos in a deep depression, but upon emerging from it, he came to believe he alone could defeat the Dark Wizard. While Acheron showed little interest in another confrontation, Theos made his enemy’s existence public, rallying followers determined to see Acheron destroyed. Their conflict reached a peak at the Eye of the Storm, where Acheron, wielding the power of Prometheus, fatally wounded Theos. The overwhelming force of Prometheus, under Acheron's control, forced Theos to push his Phoenix Magic beyond its limits, evolving it into a twisted form, a transformation Theos himself described as corrupted.
Arthur, the Cursebeard[]
As the captain of the One-Shot Pirates, considered the most powerful and dangerous pirates in the world, Arthur the Cursebeard and his crew were one of the biggest obstacles to Acheron's plan to take over the world. Just like he did to everyone else who stood in his way, Acheron showed no mercy to Arthur and his allies, doing everything he could to kill him during their battle. Although the two did not have much dialogue, Acheron likely looked down on him and thought his efforts were pointless, as always.
The Peacekeeper[]
While resurrecting Ramses II and the other dead in Savaria to gather an army for himself, Acheron unknowingly gives a peasant the greates magic potential ever seen in a human. However, little did he know is that this villager would soon become his greatest enemy, a hero known as "The Peacekeeper".
Acheron, who was unaware of his existence for a long time, began to pay attention to him as he grew stronger and became a disciple of Theos, eventually declaring him his enemy after killing Ramses II. In time, Acheron, realizing that the Peacekeeper was his greatest threat, began to harbor great hatred and contempt for him. He was prepared to do whatever it took to stop him from ruining his plans, just as he has done with all of his other enemies. However, despite all this, he was ultimately defeated in the final battle. After this, realizing that he no longer had any chance of winning, he blew himself up to not leave the victory to the Peacekeeper, a final move to protect his honor and to ensure that his enemy could gain nothing from him.
Arcane Government[]
Acheron despised the Arcane Government because he wants to rule the world, but the A.G. has gotten the better of him. In revenge, he resurrects sunken ships that cannot be sunk and places his undead armies on them, making it harder for them to enforce their laws in the Seven Seas. Acheron has not bothered with the A.G. much, as they are not much of a problem compared to his other enemies, as even a fraction of his power has kept them busy for a long time, and he had bigger problems to deal with.
His Undead Army[]
Acheron never cared for his armies, never once thought about them, let alone had a relationship with them. To him, they were merely tools to help him achieve his goals, and no matter how many were destroyed, they could easily be replaced, even though they all were indivisuals with their own will at once. His only concern about his army was their strength, as he especially chose powerful figures to resurrect them and make them a part of his army.
Powers & Abilities[]
- Genius-Level Intelligence: Acheron appears to be a rather intelligent person. He has shown extraordinary feats of intelligence, from the powers he acquired through his research on magic and sea curses to his strategic intelligence and effective use of his army and minions.
- Necromancy: As one of his most powerful abilities, Acheron can resurrect anyone he wishes through necromancy magic and bring them under his control, so much so that even the Gods themselves were not safe from this magic. This power served Acheron most during his fight against Cursebeard; otherwise, he would have suffered defeat much sooner.
- Magic Absorption: As the first curse Acheron acquired, this Curse is incredibly powerful, surpassing most other curses in its potency. Thanks to the Curse of Absorption, Acheron can absorb the magical energy and powers of his opponents. Any mage weaker than him will fall instantly due to the power of his Curse. However, it works differently on Sea Curses; in order to fully absorb the Curse, the target must first physically consume it, or Acheron will be unable to use it on them.
- Magic Bestowal: Acheron can transfer some of his magic to other people, increasing their magical power or giving them new powers, such as when he gave Ramses II some of his sand curse.
- Insanity Inducement: Acheron can not only take over people's minds, but drive them completely mad/insane. The best example of this is when he manipulates the minds of aspiring mages in Savria. He can manipulate their minds by making them see non-existent things, such as hallucinations, and the higher the insanity effect, the more deadly it becomes.
- Invulnerability: After Acheron became a spirit, he was rendered completely immune to physical attacks as he no longer had a physical form, and non-magic based attacks no longer worked on him. However, magic or sea curse based attacks still worked on him, and since they were used more frequently, this ability did not give him a great advantage in his battle with the Peacekeeper.
- Immortality: After shattering his body and turning into a spirit, Acheron managed to become immortal, and could not be killed by normal means and could naturally live forever. Him living for over 300 years and being invulnerable to physical attacks for example.
- Nigh-Complete Arsenal/Majority of Magics in the World: Acheron, who spent his life searching for magic and curses, had managed to get almost all of the magics in the entire world on his side, having control over nearly any kind of Magic/Sea Curse. These include Fire, Lightning, Light, Wind, Earth, Water, and Shadow Magics.

Trivia[]
- Acheron was originally named Durza, after Durza from Eragon. During the Port Mistral update of 5/31/2024, he was renamed to Acheron to avoid the association.
- His name comes from the river of the same name from the Greek mythology, which is described as the River of Woe and Misery of the Underworld, which fits the nature of Acheron.
- Acheron's original design for Arcane Adventures, despite being designed to accommodate his being both a spirit and able to use all magic, was not well-received by most fans of the game, with many preferring his version in Arcane Reborn.
- The name of Acheron's theme, "Order & Creation," may be a reference to Acheron's desire to take over the world (order) and him creating even stronger magics in his quest to obtain all the magics in the world (creation).
- Despite being the main antagonist of the story, Acheron is barely seen or mentioned throughout the game (both in the original game Arcane Adventures and the remake Arcane Reborn), as his only mentions are in journals written by Randal in Arcane Adventures.
