Caleigh is a supporting character, secret true antagonist, and optional end boss in the 2004 parody fantasy video game The Bard's Tale.
She is introduced as a damsel-in-distress, an beautiful princess captured by an evil cult. Promising wealth and sexual gratitude, she convinces the antihero protagonist Bard on a quest to rescue her from captive and then aids him with her magic.
At the end of the game, however, it is revealed that "Princess Caleigh" is really the Queen of Darkness, a giant demon queen ruling the underworld and trying to enter the human world to conquer it with her monster army, and the supposed bad guys have been really trying to stop her all along (for a thousand years, actually). The Bard is then given a choice to side in the final battle with either them, her, or with neither (just leaving them to each other). If he chooses to fight as her champion, she genuinely falls in love with him, resulting with a happy ending for them both (and a bad ending for most else) as they rule the world together.
