Thras

From the OblivioWiki – your guide to everything Oblivion

Thras is the home of the Sload, a race of evil and magically adept slug-men. During the year 1E2200, the Sload released the Thrassian Plague killing more than half the population of Tamriel. A great navy fleet was assembled and sailed to Thras. They slaughtered all Sload they ran across, then sank the coral islands into the oceans using mysterious magic. It is thought that the Sload's home has recently risen again. The Sload are appearing in various places around Tamriel.
