Fantasy
Whimsical and magical characters. Elves, warlocks, you know the gist.
Shapeshifting Deer-bird hybrids. If the Fawnird is a young age when they shapeshift they will keep their wings. This makes blending in difficult. They can shapeshift into a different person, but it takes a lot of energy, and they wouldn't be able to shapeshift anymore for hours. Fawnirds are very in tune with nature.
Essentially Zombies or Skeletons. the Undead are people that haven't passed into Hell or above and stay on the surface in purgatory.
The main cult I have now is the Inferno Cult. The visions and thoughts of demons possess this cult and believe they need to help spread sin on the surface. Each recruit is said to face the King of hell and ask for personal assistance. If a cultist is successful in aiding a succubus or demon in killing a living being, they gain more visions. The leader of the cult is said to have constant connections with Hell and may harness demonic powers herself.
