For TLC I more just have varients of certain mythological humanoids.
For example, Braiden and Anna are a zombie and ghost respectively:
in TLC undead are more based on the way they died, with zombies having diead of diease and ghost having died of starvation.
The blacks are also a family of shapeshifters!
Theres also Vampires, Gorgons and more, but those won't be sowing up for a little bit
If you'd like to see my different take on these and more check out TLC!
