The roots of the Order lay in the Lore of the original Inhabitants of eastern Eriador, especially Rhudaur.After the Fall of Beleriand many refugees had returned to Eriador and made themselves rulers of related tribes.One of these Tribes was known as the Arvandor and ruled what was later known as the Trollshaws. When the Númenóreans returned to Middle-Earth and the Elendili started to colonize Eriador they fought the Dark Cults that had evolved in Rhudaur at the time and subjugated the Arvandorian Tribesmen, but diverse superstitious traditions survived amongst the Eriadorians.
