Bethesda's latest trailer marks the official announcement of The Elder Scrolls V: Skyrim's latest add-on, Dragonborn. Teased last Friday and leaked a few weeks earlier than that, Dragonborn returns Elder Scrolls faithful to the island of Solstheim, first shown in The Elder Scrolls III: Bloodmoon. Dragonborn isn't about an island, however, it's about a person. Specifically, it's about the first Dragonborn.

All we're shown of this first Dragonborn is a mask to accompany this small introduction:

"He was once one of them, the Dragon Priest. He ruled here in their name, ruled over Solstheim, but he did not serve the dragons -- he devoured them. And like them he seeks to return."

Featured in the trailer are also an assortment of new environments, enemies, and also the rumored ability to use a dragon as a mount. Needless to say, Solstheim is a world apart from Skyrim. Cthulhu-like monsters and demon looking things that puke black tentacles, goblin-like folk riding giant boars and humanoid mud people with glowing orange eyes. Dragonborn appears to deliver a new world for players to discover, an add-on that truly fits Skyrim's scope and scale.

Disappointing for some fans, it appears Dragonborn will be a timed Xbox 360 exclusive much like previous DLC. Expect it to hit Xbox Live on December 4 for the full package price of 1600 MSP ($20). Release on the PC should follow about a month after the 360's debut, and PlayStation 3 fans should probably just not think about it for the time being.
