History of the Order of Keepers (Lorica)

Formation
The organization that would eventually become the Order of Keepers was the Ordera Purgatoria. The Ordera was formed as the suppressive arm of the Order of the Concord (now known as the United Guilds), upon the urging of Myrn (of) Mercadia, the Concord's Hara Syndica, in 2799 AL, roughly a thousand years before the present day. Under the leadership of the Maestra Granda de Ordera Purgatoria, Lucenus (of) Mercadia, the Ordera destroyed over three dozen competing, "heterodox" sects within the span of two decades.

The organization was dissolved and replaced, thrice in its long history; in its most recent and most long-lasting reincarnation it is named the Order of Keepers in 3259 AL, as (re-)founded by Archmage Trevelian the Elder of Aeutaril. The organization was later officially renamed the Proliferation Suppression Order in 3625 AL, though in deference to its long and glorious history and its significance in shaping Ethayan society, in common discourse it is still called the Order of Keepers.

Involvement after the Third Detariyan War
The Order of Keepers was reassigned after the end of the Third Detariyan War in 3840 AL, to suppress the burst of sects arising in the aftermath of the end of the manasapper scourge. These new sects had only weaker, cruder spells at their disposal. Thus the Order was very successful, annihilating all these heterodox sects within a single year, the revelationist Altariya College among them (destroyed 3841 AL). Thereafter some of the Order went on to help found new guild holds in now-conquered Detariya, while the rest returned to Ethaya.
