The Empress of Aeser

Still, you're not going to hold a thing like that against her. She can't help what she was made to be. The Shadow's curse twisted her into an automaton in service of the previous empress, after all, but it's not her fault she wants to restore an old dark empire.

If you can find a magical cure, the Empress' Shadow doesn't have to die. Your employer will be happy and you will be happy because the Shadow will stop trying to kill you. It's a win-win all around.

How hard could it be?
