World of Yullaara
The great she-beast, Yuulaarryy, formed in the Void from the Immortal Flesh. Being lonely the she-beast formed a womb to grow others like herself but the monsters she bore tore through her womb and killed her. The organs of her dead body, also being composed of the Immortal Flesh, formed into beasts that fought and consumed her young. Yuulaarryy’s husk was eventually used by Archos and Nef to form the world, Yullaara.
