Ancestries in Ozperia.

Humans make up most of all Ozperians. Most other ancestries would NEVER live here, especially Elves, who are really angry with the way the Houses treat nature. The other big demographic is Rat aspected Beastkin. They are actively hunted as were rats.
Fleshwarps (Ancestry Guide p.88) are a humanoids changed forever by the strange environment in Ozperia. Some are former humans getting to close to the strange radiation also known as "The Glow", others are born as fleshwarps.
These oddities are concidered holy by an even stranger cult of The Glow (if that is even possible) known as The Wyrd.
Ratfolk are the offspring of were rats stuck in Hybrid Form, or 2 Ratfolk.
