Yeen is a ruined city on the northen coast of Sothoryos. Its is near the point on the Zamoyas River where it turns into a delta.
To the north is the ruined city of Zamettar.
The origins of Yeen are one of the greatest enigmas puzzling maesters and other scholars. Like the Toad Stone of the Isle of Toads, Yeen is built entirely of oily black stone, in blocks so large it would require a dozen elephants to move them. Yeen has remained in desolation for many thousands of years, yet the jungle surrounding it has scarce touched it. Every attempt to rebuild or resettle it has ended in horror.
During the year spent in Sothoryos by some of Nymeria's ten thousand ships, Rhoynar settled in Yeen, where they had to contend with constant attacks from "brindled ghouls" from the jungle. At some point a boat was sent from Zamettar to Yeen, only to find that all men, women, and children had vanished from the city. According to tales, Nymeria called it "a city so evil that even the jungle will not enter."
