Reliquary

The Reliquary appears as a primarily blood elven organization introduced in World of Warcraft: Cataclysm, serving as the Horde's counterpart of the Explorer's League.

Background
Thousands of years ago, long before the Scourge came, the high elves of Quel'thalas formed the Reliquary. Its purpose was to find and seal away dangerous artifacts, though following the Scourge invasion, the Reliquary itself was crippled.

Years later, Grand Magister Rommath returned to Silvermoon, and oversaw the reconstruction of the shining blood elf capital. Around this time, the Reliquary was reformed.

Current activities
Today, resurrected at the behest of an unknown council based in Silvermoon and under the leadership of High Examiner Tae'thelan Bloodwatcher, the Reliquary has resurfaced to support its Horde allies, to honor its past, and to continue the task for which it was created - the aquisition of powerful magical artifacts. Though still a mostly blood elf organization, the Reliquary also welcomes other members of the Horde, notably the Forsaken.

They are dedicated to uncovering magical and arcane artifacts, operating around several new and revamped areas such as the Blasted Lands, opposing their Dwarven counterparts to the point where overt hostilities erupt. The Horde Archaeology trainers are members of the Reliquary. It was initially believed that the Reliquary would hold a major presence in Uldum, but so far only Belloc Brightblade has had any visible involvement.

Speculation

 * It was stated that the Reliquary's revitalization was at the behest of an "unknown council" based in Silvermoon. This could refer to a number of things, such as the "council" of sorts that Lor'themar Theron, Halduron Brightwing and Grand Magister Rommath hold within Sunfury Spire - or perhaps even a reborn Convocation of Silvermoon.

Trivia

 * The main headquarters of the Reliquary is located on the west side of the Royal Exchange right next to the Inn. Prior to the Cataclysm the building had been unused, being a simply empty building with a few objects. Since then it now has several Reliquary members there along with many crates along the walls.
 * The Reliquary's tabard is unclear, as their banner appears to be the standard Silvermoon City phoenix symbol. Doranir however, a Reliquary member based in Silvermoon City, sports a unique tabard (a retextured Silvermoon City tabard, with two cupped hands around what appears to be an artifact) -- perhaps the Reliquary's true symbol. There's also an icon, similar to this design, marked as Reliquary Tabard within the game files.
