Mysterious Stranger

The Mysterious Stranger is a spirit of pure darkness from the Darkness realm that comes to the world of Lore to rid it of the "pollution" of light. He is also the main antagonist of DragonFable Book 1.

Arrival
The Stranger arrive at an unknown date to Lore and has begun setting up his master plan of purging of Light from this world.

Sometimes after Alteon's rebellion, the Stranger offered a heart-broken Sepulchure the DoomKnight armor along with the Necrotic Blade of Doom so that he could gain more power. While Sepulchure did receive the power he's been craving for so long, his mind and body was poisoned by the armor until he becomes a puppet for the Stranger.

To Falconreach
After hearing about the Hero arrival in Falconreach, the Stranger comes to the town so that he could aid them in order to further his plan.

There, he sold and upgraded Dooms weapon to adventurers unaware of their power in exchange for an outrageous amount of gold and soon became the town residence mysterious merchant.

Rise to Power
The Stranger appeared after the Hero and Sepulchure defeated Drakath the Darkness Dragon and informed the two of his intention to destroy Lore before bound himself with Drakath and become the Super Mega Ultra Darkness Dracolich.

The Stranger then issued a call to all the creatures of darkness hiding around Lore to join him and grow his strength. They answered, and his mass began big enough that his shadow enveloped the continent and he was able to eat the sun.

Despite the overwhelming odds, one town remained free of his taint, Falconreach, the very town in which he used to reside.

Defeat
His - almost - victory is short lived as The Hero and their dragon arrived with the Ultimate Bacon Orb and challenged him into a battle that will decided the fate of Lore.

Despite putting up a good fight. The Hero couldn't defeat Super Mega Ultra Darkness Dracolich as it's regenerating after every blows. However, the turning point came when Fluffy reached out to them within Super Mega Ultra Darkness Dracolich and told them to destroy the orb and let out the sun.

Ultimately, the orb was shattered and the sun destroyed the Super Mega Ultra Darkness Dracolich from within. While the damages done to Lore will be repaired in time, the Mysterious Stranger was presumably gone for good, although this is not known for certain.
