Nightmare Realms

The theory of the Nightmare Realms proposes that reality is not singular, but rather plural, with there being countless other realities, all striving towards Perfection, a state of reality in which everything is at it's peak potential and thus cannot be improved. The countless existential planes that are said to exist besides Perfection and Imye Thir are called the Nightmare Realms, called so because of their innate connection to human dreams and nightmares.

The theory, first proposed by Zapatushtra 'the Ingenious' and then expanded by his son, Zapatushtra the Younger, subsequently became a bone of contention in sahemic communities all over the world. Currently it is considered to have been mostly proven, with some details that are unaccepted by the sahemic community as a whole omitted from official doctrine.

Known realms
The theory preaches that there is an infinite number of other worlds, all imperfect in some way. There are some existential planes that are known to us, described by the few people that claim to have visited the Nightmare Realms:


 * Hallowed Heaths - described as a beautiful world full of unending moors and heaths with one of the visitors claiming it to be "a facilely charming world, yet eerie and unsettling in it's quietness". He also added that "something terrifying is romping through the heathers, deep inside".


 * This Man - probably the most cryptic world, two adventurers claimed to be in a man that they then drew with terrifying accuracy. When asked if he was the inhabitant of the world or it's ruler, they simply answered that "he is the realm" and that "the entire world is the man, there is nothing else but the man".
