Dawn of Darkness
Deep Duerra, also known as Queen of the Invisible Art is the duergar demigod of psionics, conquest and expansion.Deep Duerra and her clerics were known below the surface as Norothor (“those who seized enemy lands”).
The older duergar who served Laduguer considered the Norothor to be a nuisance, because of the strong degree in which they preached expansionism. Regardless, the Norothor served an important role in duergar society, since the trained the natural psionic abilities of young gray dwarves.
In the stories of old duergar mindwardens, Duerra was the queen of a dark and imeense subterranean dwarven empire in ancient times. In their expansionist wars, the queen herself stood in the front of her armies.
On one campaign leading to the domination of a huge illithid city. Duerra ordered her men to capture the mind flayers. After a century of work, Duerra and her surgeons succeeded in taking the psionic powers from the captive illithids and transfered it into her brood and her cal’s bloodline. Many duergar honor Duerra as the progenitor of their psychic abilities.
