The Abyss, Home to Yggdrasil: The Everwant Tree, The World Tree
Wergelmir is home to the Everwant Tree, also known as Woddrasil, the World Tree, and the Pillar of Mankind, is worshipped by many who still follow Gods of old, those Gods who died or abandoned their post when the Aboleths enslaved their creations. Those who center their worship around the supernatural tree rarely understand its true maleficent nature, or choose to ignore it, and venerate it as the pillar on which our world exists, a necessary force of nature, the source of all life.
Many view this world and all others to be the leaves of the branches of Yggdrasil, fed by the tree until it can no longer bear us, at which point we are shed and devoured by the serpents at its roots, a death necessary to sustain the rest of the tree. This mindset is perverse, however; rather than the leaves of the tree, we live in the cosmic soil, the roots of the tree seek out our world and others to draw power from us until we are completely drained, feeding not us, but something much more frightening.
The worship bestowed to the tree is a complete farce perpetrated by those who live in its leaves, the Demons. The Demons visit new realms yet to be touched by the roots of the Everwant, and plant within the minds of the beings living there the idea of a World Tree necessary for the existence of this world and others. This worship acts as a beacon to the tree, who can extend its roots into this realm and prepare to destroy it so that it may make more of its own worlds. It will not cease until the last world is killed and its bones are used to craft a new world.
The worlds devoured by the Everwant go on to be corrupted into something sinister, joining the ever-expanding infinite of what we call the Abyss. Many refer to the Everwant as the God of Want, though its status as a God is somewhat contentious. Thankfully, the tree appears to hold no real power over a realm, and relies on the world destroying itself. To do so, it must invade the minds of the life of the world and convince them that the tree is worthy of worship and subtly guiding them towards destroying themselves for the good of all other worlds. The amount of worlds this has already happened to is unknown, as layers of the abyss are often empty, claimed by no one, and are never discovered.
Currently, the Church of Iggdrasil is scarce, scattered, and split, and can barely be called a church. Half the church simply want to venerate the tree as the life giver, and the other half call for the end of this world to give way to a new one. The latter worship demons as Gods of rebirth and true Human nature, wealth, hunger, desire, and so on. They preach about the supposed warmth and unity that would come with being consumed by the tree, while in reality, the tree want nothing more than to dissolve this realm into nothing before crafting its own vision.
The Devils have a particular hatred for the World Tree, as they value a certain order to the universe, whereas Yggdrasil claims worlds indiscriminately. While Devils believe there should be a strict structure to the rule of worlds, with the weak governed by the strong and a clear line of hierarchy, Demons instead call for the wanton destruction of worlds for the expansion of the Abyss, with little care for hierarchy or installation of a ruler.
