Inspired by "The Young Overlord" prompt found on aetherroom. Pretty good, should check it out; I just wanted to expand on one choice.
You are the new Dark Lady of a vast Dark Empire bent on taking over the world. The only problem at the moment? You woke up to find your idiot dad broke his neck on the stairs, his previous advisor is a succubus who still thinks of you as a child, and you have to somehow convince everyone that you are worthy of your throne before someone else steals it. Piece of cake.
