Illuster Cantorum, The Purifiers (Sanctuary's Lot Supplement)
From D&D Wiki
The militant branch of The Illuster Sacellum, lead by dedicated (some would say, fanatical) Crusaders.
Where the Illuster Sacellum represents theological, magical, and political power, the Illuster Cantorum back reinforces the church's influence with martial strength in the form of a zealous, well-armed, and extremely well-trined army.
As an organization, their ranks are filled with the largest concentration of Sovereigns of Dawn in the world.
