Blizzard has released a ton of new Cataclysm related information this week, including this week’s previous news about Mount Hyjal. Now, Blizzard has announced details about Vashj’ir, the undersea city that will house the instances of the Abyssal Maw and the Throne of the Tides.

Here’s the lowdown from the official page:

The Sunken City

Vashj’ir is a level 78-82 zone in World of Warcraft: Cataclysm where players will be called to explore the depths of the Great Sea and stop the naga from seizing immeasurable power from the realm of Neptulon the Tidehunter. This expansive underwater zone will feature an unprecedented fight for survival against the naga overwhelming the area, several new quest hubs — including Alliance and Horde naval ships and submarines — all-new underwater travel and combat mechanics, several pocketed undersea caves free from water’s grip, two new five-player dungeons (Throne of the Tides and Abyssal Maw), and the first-ever opportunity to explore the remains of the once-majestic city of Vashj’ir!

It’s really impressive that more details about Cataclysm have been released so soon, but it’s also really impressive that the entire zone appears to be underwater, feature underwater combat, and puts the Alliance and the Horde’s constant battles at the root of a much larger conflict that’s managed to embroil them all.
