Inspired by a line in Vash's Lust of a Dark Soul "...the days of the great sorcerer kings will return..."

Summary:
Write an AU in which the world, wizarding and muggle, is ruled by sorcerer kings.

Rules that must be kept:
- Has to keep to HP magic system.
- Has to follow Harry or a little known character (i.e. no Ron, Hermione, Ginny as the main character).

Suggestions:
- Dumbledore could be the sorcerer king of one nation, Voldemort of another. (Dumbledore being a good ruler and Voldemort being evil.)
- These two nations could be at war, or leading up to war.
- Voldemort could have been Dumbledore's apprentice before going evil.
- Harry could be the apprentice to either Voldemort or Dumbledore.

Obviously you don't have to use all the suggestions, they're just some thoughts I had.
