Path of the Wanderer
Amur is both the name of the entire world, as denoted mainly by the dark sphere that marks the habitable boundary of creation, and of the deity which is synonymous with that world. Amur is used by different people to refer to only the sphere in which all life exists; or to the sphere and all things in it; or to some mix within. Some hold that each of the Thirteen is distinct from Amur, while others assert they are no more distinct than a hand or a leg is distinct from a person. Amur the deity is never assigned a gender, age, appearance or even an inclination. It is the primal deity, from which all others sprang or were birthed or created, at some distant time; the exact means varying with each other, ostensibly lesser divinity. Amur is held to have little or no interest in the world as a whole; it is the world, after all, and the tiny goings on within itself are not considering important to the being, according to the learned. There is no clergy of Amur, though there is a priesthood, small and much ignored, which in obscure corners of the world prays to a being that doesn't respond, and which many assert is either moribund or imaginary. Much more common in the day to day world is the mention of Amur as the world; its godhood is nearly ignored.
Swearing with Amur's name is not uncommon however, usually in improbable ways: Amur's tits, or Amur's hairy ball sack, are both used. It is held that nothing will be offended (save Amur's minor priesthood, about whom no one is much concerned) and the inherent irreverence of assigning genitals to a being which, even if it existed, has none, does not fail to amuse the simple.
