Worldofwar.net has an article about the lore behind Isle of Kezan, the homeland of the goblins located in the South Seas. This article is in response to the recent rumors surrounding the new trademark filed by Blizzard Entertainment. Cataclysm matches perfectly with events that transpired in Azeroth ten thousand years ago which caused the Great Sundering and the implosing of the Well of Eternity. The scar of that cataclysm is known as the Maelstrom, a vortex of raw arcane magic in the middle of the Great Sea.
