Anfauglith
From Tolkien Gateway
Anfauglith was the charred desert to the north of Beleriand, created by the fires of Thangorodrim during the Dagor Bragollach ("Battle of Sudden Flame") in First Age 455. It was originally the green plain of Ard-galen.
Anfauglith means "By Gasping Dust" in Sindarin (from an- = "with, by", faug = "thirsty, gasping", and lith = "ash, sand, dust").
