A beautiful Empress lived in a moonlit castle by the sea. Each year she blessed the land that she owned, and rewarded her loyal subjects with long life. But sometimes, she came at the winter festival, to take a spouse.

Arlen had always been fascinated by the dark Empress, and he was excited to be picked. Little did he know that his curiosity would be the cause of his end....

Seth never forgave the Empress for the taking of his friend, and swore revenge. At last, after many years of waiting, he offered himself in disguise, pretending to be a lord from another realm.

He entered the Moon Palace with plots of revenge in his heart, but before long he must choose between loyalties and fight unknown dangers to save the castle from destruction, and save himself.
