The Divines of Rebma are something like a church and something like a public utility.

Every initiate of THE GLOW is automatically an 'ordinary' member of the Divines. The Divines use the Glow to maintain the habitable undersea environment of Rebma and defend the city in the event of an invasion. Every initiate is subject to mobilization on the Queen's orders or on those of the Archdivine, the head of the organization.

The Divines have the Queen at the apex, then the Archdivine who actually runs the order -- currently Teleri ap-Olwen, then the First, Second and Third Circle of Divines, then acolytes.

Divines do not sever their ties to their families. Playing family politics within the organization to the detriment of its function was worth a death sentence under Queen Moire.
