Bethesda has released the first Oblivion expansion, The Elder Scrolls IV: Oblivion – Knights of The Nine, is now available on the marketplace for 800 Microsoft points, or $10. The expansion brings along around 15 hours of additional gameplay, including:

• Begin a New Faction – The Knights of the Nine have long been disbanded. Reclaim their former glory as you traverse the far reaches of Cyrodill across an epic quest line.
• Battle New Foes – Encounter Umaril, the ancient Ayleid Sorcerer-King, and his minions, the fearsome Aurorans.
• Discover Unique Items – An entirely new armor set and weapons, each with unique powers.

The PC version will be released on December 4 and can be bought on the official website, and will include all the content released on Xbox Live so far, including The Vile Lair and Wizard’s Tower, among others. The PS3 version will have all additional content included when it comes out early next year.
