Y Branch
The Y branch is run by "Symbiote spirit animals", aka. the animal souls can choose a human or another animal to bond with, which sometimes the human knows about and sometimes doesn't, which then enables the animals to become "real". This is thought to be where the first wereanimals were recorded.
These symbiotes are known as uniotes
This world is full of humans... Yet deities walk among them. Or rather, deities use the humans to walk.
Yes, this is inspired by Moon Knight. Yes I'm too obsessed with it. It's a problem.
Here, there be werewolves
This world may be populated and ruled by humans upon first look, but look under the serface and you will see the wolves. Here, the wolves are disembodied entities who use humans as avatars. The wolves see the real world as an afterlife, where when the entity dies they take on a human form with no memories of who they were before.
A group of noble wolves, known as Anubis, set up the Legion of Canis on this world to protect it from the rogues, whom they deem unworthy of this afterlife.
Both Anubis and rogues use humans as a means to move around. Anubis only take those in the Legion as an avatar, whereas rogues will take anyone.
When in wolf form, the human can remember nothing of what happened. Many humans have no idea they even have a wolf entity living inside them.
Zombies.
But not the classic zombies. These guys are lost souls, never taken to the Afterworld. The attach to hosts and verrrrryyyyyy slowly take over.
