The Dawning Isles
The Dawning Isles used to be an idyllic set of low keys that rose from the crystalline surface of Lordamere Lake, but had been affected by the Plague of Undeath. The trees grew sickly, and dangerous murlocs and bog beasts roamed the islets. The bog beasts have since vanished and the Vile Fin murlocs are grown to a very large population taking control of the isles.
The isles were taken over by the Scarlet Crusade. They mounted an attack on the Ruins of Lordaeron, and the Forsaken tried to counterattack.
