A beautiful queen rules her country with an iron fist. Unmarried and without an heir, she adopts orphans as a way to prove that even commoners can reign as kings. Yet, as the years progress, she shows no sign of aging. Only one man knows the dark secret to her eternal youth: Oldman, a bearded magician the queen has locked in her darkest dungeon. One night, Oldman steps through the bars of his prison and disappears before the queen's very eyes. Having tricked the guards (and not actually having left the dungeon), he rescues a neighboring prisoner, a sword maiden rebel whose arms and legs were amputated, and left to rot in her cell. Together they vow to take revenge on the Queen that wronged them.
