Celeste

Ardythe, a hardened female warrior and assassin, is sent on a mercenary mission to find a legendary cursed castle and kill its lord. She is surprised to find Aurelian, a young and beautiful magician alone in the fortress. The two vie subtly for control, and eventually engage in an all-out battle for sexual dominance. Ardythe must deal with her strong feelings of attraction (even love) for Aurelian, her assignment, and the mysterious being called Celeste, who is Aurelian's source of power, lover, and captor.
