Mother Vortex is an enormous tree that rests in The Vortex. She powers the island through her roots. The island she controls is called the Animal kingdom; it is uninhabited by humans.
Mother Vortex has a root connecting to AETA's spiritual tree, that contains falled soldier's spirits, preparing them to go to heaven, and in the fall, they go.
All the roots combine and hold up the islans and create fog around it so no humans spot it.
