Blizzard Entertainment announced on the 8th that the Siege of Orgrimmar content update has been applied to World of Warcraft: Mists of Pandaria Classic.

This update introduces a wealth of new content, including the Timeless Isle, the multi-stage Siege of Orgrimmar raid, five new world bosses, the final steps toward the legendary cloak, and the Proving Grounds.

Beyond the eastern shores of the Jade Forest, a mysterious island long forgotten and unbound by the flow of time has emerged from the mists. The Timeless Isle is filled with powerful enemies, hidden treasures, unique creatures, and unpredictable events that will test the skills of even the most daring adventurers.

The new Siege of Orgrimmar is a massive, two-part raid that takes players through the devastated Vale of Eternal Blossoms and into the heart of the Horde capital. Heroes must first confront the corruption of the Vale caused by the Heart of Y'Shaarj, then break through Orgrimmar's defenses to face the Warchief directly.

Additionally, powerful world bosses tied to the trials of the August Celestials await on the Timeless Isle. Each battle embodies the teachings once faced by Emperor Shaohao.

More information on Mists of Pandaria Classic, including the Siege of Orgrimmar update, can be found on the official World of Warcraft website, and related image assets are available in the press center.
