What is Alexander?

[Sexbad]

Hints, Help, and Spoilers section with this one.

We know he's from another place, as most people would call a "dimension" different from our own. Somehow he crashlanded into ours with a bunch of his otherworldly shit (orbs, the Shadow, the waterlurker, blue fire, etc) and was separated from his love. He vows to get back to his loved one by any means necessary, and since he is magical and stuff, he can gather energy from human souls through their blood. He also attempts this on animals, as seen in the Study level as well.

Since he had fancy powers he was able to take control of part of the Prussian government and build a nice castle to make mincemeat of all his victims and some not so nice servants to gather such victims for him.
