The Elder Scrolls Online was just revealed to be ZeniMax Online's long-rumored MMO. Game Informer's next cover announced the game this morning. The mag says The Elder Scrolls Online will take place across the "entire land of Tamriel," approximately one thousand years before Skyrim's place in time. The story will focus on daedric prince Molag Bal as he attempts to make Tamriel part of "his demonic realm."

The game's director is Matt Firor. "It will be extremely rewarding finally to unveil what we have been developing the last several years," he says. "The entire team is committed to creating the best MMO ever made - and one that is worthy of The Elder Scrolls franchise." The game's July cover reveal will detail a variety of the game's possibilities: soloing, public questing, and a unique new take on player-vs-player, in which the three factions battle over sections of land or a desired position of power.

More will be revealed tomorrow in a "brief teaser trailer" of the game, GI says. We've got our double-horned helm on while we wait, just in case.

Update: Bethesda's PR says the game will launch for both PC and Mac.
