The tribes that later became the Wainriders originated in a Land east of the known Rhûn called Lotan but moved westwards later and settled in the lands surrounding the inland sea.The Sagath, Logath and Igath were considered to be part of the Wainriders -all tribes of Ulgathig descent, while the other related tribes as the Urgath, Brygath and Gathmarig had long merged into the Igath by that time.They were worshippers of Sauron whom they identified with Kerkassk, the plains-god.The Igath-Wainriders, by 2950 TA, had become part of the Variag-Realm of Khand.
