Laduguer

Laduguer, also known as The Exile, the Gray Protector and Master of Crafts is the lawful evil dwarven god of the duergar. Ever since he branched off from the rest of the dwarves, Laduguer has harboured a bitter resentment, viewing the rest of the pantheon as layabouts more concerned with outdated tradition than with progress.

However, his doctrine teaches obedience to one's leader, empowerment through the exploitation of slaves, enrichment through the creation of magical weapons and protection through an unforgiving military program. He is xenophobic, urging his followers to avoid contact with other races save for limited trade and slave raids.

Worshipers
The duergar do not differentiate between secular and religious authority, so Laduguer's worshipers serve as the nominal rulers of society. They are known as the thuldor - a dwarven term meaning "those who endure" and they keep the race united and powerful against the other races of the Underdark. They are expected to serve in the military.

Many temples include large stables used to care for and breed steeders - large, monstrous riding spiders.

Relationships
Laduguer is at best tolerated by Dugmaren and Sharindlar - the rest of the pantheon hold him in deep scorn.

Deep Duerra, thought to be his daughter, is his only true ally - and even she hatches many schemes against him. His race's dominance over the trade of steeders has gained him the enmity of Lolth and he has ancient disputes with the demon prince Orcus.

History
Laduguer has been exiled from the Morndinsamman. The gold and shield dwarves claim he committed unspeakable crimes and was only saved from Moradin's wrath by Berronar Truesilver. The grey dwarves, however, say he was an advocate of righteous, innovative philosophy that offended Moradin so much that he cast him out.
 * 1383 DR : Laduguer, along with Deep Duerra, is destroyed . Hammergrim disperses into the Astral Plane . Most Worshipers of Laduguer did not realize this, however, as Asmodeus took up the guise of Laduguer in an effort to gain more followers. Duergar began making pacts with devils as a result, securing infernal power for themselves.
