Tales of Corvus

World is post-war. Elves were the reigning race, but were overthrown by the humans for the magical curative properties of their blood. Also speculated to elongate human lifespans if consumed in excess.

Elves were captured and enslaved by the humans after losing the war. The ones who lived mostly fled to the holy lands and built a barrier around it to keep their enemies at bay.

World is a mix of fantasy and futuristic.

There are werewolves and other races besides just humans and elves.

Elves likely descended from eldest race, whom created the various ruins scattered around the world. They had far more advanced technology than what is current, but most of it was lost over time.
