The Crystal Hall is an area of the Exodar. The shaman trainers can be found here, as well as a small crystal-digging mine full of Broken workers. Note that the shamans aren't all draenei; there are also furbolg and broken shaman trainers around, including the most important one, Farseer Nobundo, located at the small elevated platform in the zone. The Crystal Hall also houses numerous trainers, a first aid trainer, a fishing trainer, an enchanting trainer and a jewelcrafting trainer.

Another notable NPC in the area is Seer Skaltesh, close to the enchanting enclosure. If the player talks with him, he/she is given Elemetal Sapta, which can be consumed and gives Elemental Vision to a player for one minute. While under this spell, it is revealed that there are, in fact, numerous elementals present in the Crystal Hall.

An interesting fact is that the draenei harvest crystals in northern portion of the hall, where broken ones miners use their mining picks to gather the precious gems. This part reminds one of an excavation site. The crystals are used to repair the Exodar. It is gathered that the Broken, though still Draenei in some regard, are treated like a lesser class; a labor and task force. It is kind of odd that a race with such an attachment to the Light treat those who were once their own people with such distaste. It is possible that the arrangment was agreed to by the Broken; their bodies might be better suited to manual labor than "pure" draenei.
