Arborism

Arborism is a minor religion that mainly worships a supposed being known as The Tree and it's three witch offspring. Followers wish to integrate monsters into human society and wish to become one with them. While the worshippers often leave ominous and threatening notes calling upon the destruction of all humanity they are generally relatively peaceful towards others as they do not believe in intentional murder or harm without cause. Followers often gift fresh meat and blood or even preform live sacrifices to trees in order to feed The Tree as they believe it is hungry and craves meat, preferably the flesh of these whom they consider unjust.

The Tree
The Tree or occasionally referred to as The Tree of Possibility, is believed to be one of many hive minded immortal entities which exist in another plane of existence free from the constructs of time we understand called Sirna. The Tree is only represented physically with a tree by worshipers as they believe we cannot truly recognise and fathom it's true form. The Tree is a gender neutral being and is never referred to as a god but instead beyond that of a god as the hivemind group is believed to be a semi-physical representation of every different possibility that can ever exist. The Tree is believed to contain all living souls or 'energy' from our world and has the ability to move souls between bodies, as well as, destroy or create new souls. The Tree is shown being unable to communicate with humanoid beings but is able to understand them.

Children of The Tree
Original scriptures suggest that The Tree has four children that formed from it's branches. Those being one son and three daughters who are also said to be witches of some kind.

The Three Daughters
Most of the time The Tree's daughters are written as a group and praised as a group without individual names and very few differences can be found. They are suggested to help The Tree determine what happens to a soul once they die. They are often referred to as goddesses and/or witches.

Rubnur
Within the oldest surviving text documented so far, Rubnur is the only one of The Tree's children that gives themselves a name. The god was said to be very violent and desired to rule over his siblings believing his physical capabilities a better skill than the abilities of his sister's. Eventually he is tricked by his sisters and The Tree torturously consumes his flesh and soul. It is said that all life within our universe came from The Tree absorbing Rubnurs soul and creating millions of new souls which it send to our world.
