For a majority of non-humans the aging process is extremely different from how humans age, this section will cover the different rates at which non-humans age.
Beastfolk, beast heads, centaurs, and invisible men all age the same as humans.
Nebulants, undead, gargoyles, elemental/emotional embodiments, ghosts, androids, and grim reapers do not age.
Ghouls, shapeshifters, and doppelgangers choose what age they want to appear as at any point they like.
Witch years:
1 witch year = 12 human years
Some experienced witches are able to become immortal
When a beastfolk becomes a witches familiar they will begin to age slower or can become immortal depending on the power level of their master
Werewolf years:
1 werewolf year = 4 human years
Vampire years:
1 vampire year = 1.5 human years (below 20)
1 vampire year = 10 human years (20-26)
1 vampire year = 50 human years (27-33)
