This is a short list of the raids that will be coming out for Mists of Pandaria and where they are located. They are also listed in their progression order.
- Mogu'shan Vaults: This raid dungeon is found in the Kun-Lai Summit, accessible only by air from the terrace on the northern coast (just west of the troll region). It harbors the hidden secrets of the ancient Mogu empire. From Blizzcon 2011: "This six-boss raid... invites you to explore the hidden secrets of the elusive Mogu empire, one of the new indigenous Pandarian races." According to Cory Stockton of Blizzard in March 2012: "In this raid you're actually fighting more of a ghost side of the Mogu. So as where you would be fighting living Mogu in the dungeon, here you will see a ghost version."
- Heart of Fear: A Mantid-themed raid where players will be fighting the Mantid empress, located within a huge rotting tree in the southwestern part of the Dread Wastes.
- Terrace of Endless Spring: A Sha-themed raid; a "super super huge raid boss and that whole raid circles around him and he has turned other local creatures into Sha". It also is referred to as "Terrace of Eternity" in the beta files. The raid door is located in The Veiled Stair, a small mini-zone east of the Vale.
Mogo’shan Vaults (MsV)


Mogu'shan Vaults is one of the three new raids that will be opened in World of Warcraft: Mists of Pandaria. This will be the first raid that we do when Mists of Pandaria comes out. This six-boss raid invites you to explore the hidden secrets of the elusive Mogu empire, one of the new indigenous Pandarian races.
The entrance to the Vaults is found in northeast Kun-Lai Summit, accessed on Mogu'shan Terrace, overlooking the Zouchin Province far below.

The mogu, proud of their supremacy, kept lengthy records of their accomplishments within a great complex of vaults. Guarded by ferocious magical beings, these sacred chambers have remained silent since the mogu's departure.

Terrace of Endless Spring (ToES)

The Terrace of Endless Spring is an upcoming raid in World of Warcraft: Mists of Pandaria. This is a Sha-themed raid located at the midpoint of the Veiled Stair, a mountain pass between the northeastern corner of the Valley of the Four Winds and the southern part of the Kun-Lai Summit; a "super super huge raid boss and that whole raid circles around him and he has turned other local creatures into Sha." It is a small, two-boss raid.
The meeting stone and a flight path are located just down a short hill from the raid dungeon entrance, deep within the Stair.
Four boss encounters are listed in the dungeon journal: the Protectors of the Endless, a trio of Jinyu; Tsulong, a cloud serpent; Lei Shi, a water spirit; and the Sha of Fear as the final boss.
Dungeon Journal
Straddling the mountain range between the Jade Forest and the Vale of Eternal Blossoms, the Terrace of Endless Spring has been a sacred refuge for millennia. Its peaceful fountains are said to have the power to heal and rejuvenate, but when the Sha of Fear attacked, many of the complex's guardians turned on each other in fits of terror.
