Zorath was one of seven new barbaric kingdoms formed after the destruction of the kingdom of Adar, at the end of the Fourth Age.

The realm of Zorath was located in eastern Corwyn, in what is today northwest Morgoth. Its capitol was the Darkstone Keep. The Zorathi worshipped dark sorcery, and had a dreadful reputation for cruelty and terror. The kingdom was eventually absorbed into the larger realm of Morgoth, after the rise of Sorimmar.

The last King of Zorath, whose true name is forgotten, became one of the seven Zûl, under his new master, Sorimmar. Zorath’s coat of arms was a red eclipsed-sun on a black field.
