The Order are spiritual emissaries of the One, an obscure Immortal whose ascension went largely ignored or unnoticed.

The clerics of Order are referred to as Voices. Their mission is to proselytize, convert and indoctrinate. They tend to travel in pairs for safety, companionship and to keep one another accountable and on the straight and narrow path.

When in dangerous territory, their companions are holy warriors called Hands—the Order's shock troops, tasked with dispensing truth and justice at the end of their swords.
