Rosabel

Rosabel was the main antagonist of the fantasy computer-game, Trine 2, being the force behind the ruin of the kingdom - seeking the power of the Trine for herself she tried to trick the three heroes of the game into giving her the Trine (or dying so she could take it herself) only for their continual efforts to expose her true nature and force her to fight them personally.

History
Rosabel was the sister of Isabel and together the pair were princess of a kingdom, yet Rosabel had a dark craving for power and thus betrayed her sister - cursing her to an eternal sleep and sealing her away in a mystic forest while making herself the official Queen.

Rosabel's rule was disrupted, however, as Isabel's inherent magic was leeched by the forest that held her prisoner and summoned malevolent monsters such as goblins and trolls that started to lay waste to the kingdom and thus Rosabel began to search for ways to fix this fatal flaw in her plan,

An opportunity for such a gain arose when a group of three adventurers came to her notice alongside a powerful mystical force known as the Trine and she tricked them into aiding her rid her lands of trolls and goblins.

However after the heroes defeated the goblins and trolls they learned of Rosabel's true nature and she was left with no option but to face them personally when they managed to get to Isabel herself but unable to wake her from the curse.

Rosabel demanded the heroes give her the Trine so she could bring a new age of order to the world, they defied her and claimed even if they did give her it the Trine would never aid someone with evil intent - Rosabel scoffed at this and unleashed a dragon to try and kill off the heroes.

The heroes ultimately defeated the dragon and as the beast fell it knocked Rosabel off a cliff and into the waters below, she would have drowned had Isabel not awoke from her curse and dove after her sister, rescuing her despite her actions.

The last the heroes see of Rosabel is her being carried off in Isabel's arms, it is unknown if she died or if she was taken back to the kingdom to face punishment for her crimes.

Appearance
Rosabel is a dark haired, fair skinned woman with regal beauty but tainted by the aura of tyranny, which she tries to disguise in order to gain trust but will inevitably show regardless as it is her true nature - in her true form she dresses in a much more sinister manner, with an empathise on black, which has a long-standing association with malicious witchcraft and evil forces in fantasy settings.

Personality
Rosabel was a cunning and manipulative witch who saw others as pawns by which to gain more power for herself - while she claimed to bring order to the kingdom she was reckless in her actions and thus caused the chaotic and stupid monsters such as goblins and trolls to lay ruin to her land : this in turn motived her desire to capture the Trine and bring law to the world, though such law was, of course, her own absolute power and thus she had no intention of rewarding the heroes for their servies other than killing them and her most striking display of power-thirst lays in how she had no qualms about cursing her own sister with a near-unbreakable sleep spell just to gain power and her only remorse was purely her inability to control Isabel's magic and thus prevent chaos ruining the kingdom she saw as her own property.

Abilities

 * Supreme Monarch (Rosabel became a supreme monarch and while she allowed her kingdom to fall to ruin she would still of had complete authority over all its citizenry, military might and resources - as was the case of medieval and fantasy settings : even as a princess she would of held an incredible degree of authority and sway over the common world, without the need for her other abilities)
 * Master Sorceress (Rosabel focused mainly on her great magic and was able to disguise her form, observe heroes from a long distance via a magic mirror, put her sister in a near-unbreakable sleep curse and chain her to a tree amidst a mystic forest and had extensive knowledge of mystic items as she knew of the Trine and its power, though she was convinced she could force it to her will despite the heroes telling her the Trine, as a sentient force, would never aid her in her evil ways even if the heroes gave her it)
 * Cunning (Rosabel is a cunning opponent and thus can trick others into doing things for her own benefit, manipulation and charisma being key - revealing her true nature only when all other options have been worn out and thus avoiding the cost of unnecessary fighting on her own part)
 * Dragon Summoning (Rosabel's most impressive display was summoning a large dragon to try and defeat the heroes once and for all during the final battle)

Trivia

 * she is an archetypical fairy tale witch and evil queen who has many similarities to villains such as Maleficent (the sleeping spell and her use of a dragon in the final battle against heroes), Scar (a thirst for power and betrayal of a sibling, as well as their rule causing their kingdom to fall to ruin, though Rosabel's ruin was mystical in nature and Scar's ruin was due to neglect) and of course the traditional Hags and Beldams of mythology and folk tales.
 * the imagery of brave heroes having to defeat a mighty dragon to save a hapless princess is a very common fantasy and folklore theme - though it has become controversial over time due to both the idea of it being cliched and the "damsel in distress" stereotype ; regardless of this controversy many fantasy fans still have a soft spot for these "old school" plots, Trine 2 arguably avoids the "damsel in distress" dileema common in these older tales as one of the three heroes who rescues the princess is herself a female.
