The Order of the Guardian
From Mistipedia
The Order of the Guardain is a secretive society dedicated to putting dangerous magical items, artifacts, relics, and tomes of arcane lore safely beyond use.
Members of the order may take leaves in the prestige class Guardian Seeker. The group is known to be active, and probably have bases too, in Hazlan, Mordent and Sithicus at the very least. It Sithicus it may guard an iron flask improving a fiend of immense power. In Morent it may guard the Transcendental Halo. In Sithicus it guarded the Shadow Serpent.
