As stated in the Kobold pantheon book in game, but you cant choose him.Dakarnok is the youngest of the kobold deities, and is perhaps the most fierce. He is also known as The Great Bandit, The Raider of the Master Looter and was once a mortal kobold. Before being deified legends state Dakarnok was a kobold war chief who lead a crusade from the Underdark against all humans, demihumans, and humanoids, in the process founding a kobold empire to rival all others. Kurtulmak, pleased with the kobold's achievements came to Dakarnok as he lay dying at the end of his natural life and offered him a place at his place as it side. Dakarnok accepted and became the third member of the kobold pantheon.
The priests and followers of Dakarnok believe that the noblest pursuit for a kobold is to emulate their deity; to fight, conquer, pillage, and loot. They preach that destroying your enemies through raid and outright war is the best way to preserve the safety of the home warren. to take all of value from a fallen settlement and destroy the rest as a warning to your enemies. His followers also believe in the power of wealth and hold personal fortune to be the sole measure of a kobold's worth. He is followed by warriors, bandits and strategists and his clergy often double as military leaders among kobold society.

Power level: Demigod

Alignment: Neutral Evil
Portfolio: War, Destruction
Worshippers: Kobolds, Warriors

Arelith Worshippers alignment: LE/NE/CE
Note that the two other kobold deities are both trickery and deceit.
