Church of Deep Duerra

The church of Deep Duerra was the primary religious organization dedicated to the worship and service of the goddess Deep Duerra, the Queen of the Invisible Art. They were commonly called Duerrans.

"The mind is but another material, set before us to shape into a weapon."

Rituals
Norothor prayed for spells at night. The duerran clergy had two annual holy days, during each of which an offering to Duerra was made in the form of dirt or stone from the borders of newly conquered land, the brains of psionic individuals, or the shattered skulls of any intelligent creatures.

The first celebration was a perverse festival known as the Rallying conducted on Midwinter Eve. That night, Duerra's followers came together to commemorate the triumphs of the past year and announced their intentions to expand for the coming year. The duergar worked themselves into a grim fury accompanied by the sound of dark war chants and the pounding of hammers into stone, both causing echoes through the tunnels. The culmination of these exaltations was the display of a freshly severed head of an enemy that would be passed around the group, the race of which was the next foe they planned to besiege and take territory from before the next Rallying.

The other Duerran holy day was celebrated on the 5 of Mirtul, and it was on this day that skilled Invisible Art practitioners joined together in Duerran temples to perform the Melding, a psionic ritual ceremony where the assembled duergar minds contacted Duerra herself. While in this state, the collective duergar formed a communal mind rivaling that of the great illithid elder brains, providing the clerics of the collective with many of the greater insights that led to psionic and technological advances, aiding them in their endless quest for power and dominion.
