Secret Orders: The Keepers of Common Purity

From Introduction:

Borne from extreme prejudice, the Keepers Of Common Purity hold their concerns towards keeping their communities and surrounding regions from any element that might change or alter their “way of life”. Though now the Keepers hold interest over a wide variety of social and community elements, originally the order meant keeping the villages purely human and free from the infiltration of whole or half demi-human and humanoid residents.
