Diirinka

Diirinka was the patron god of the derro,  a deity of magic and knowledge, as well as cruelty. His symbol was a spiral of gray, black, and white.

Description
Diirinka preferred to appear as a diminutive (around ) tall, stunted creature, a kind of derro-lich hybrid.

Realm
Diirinka realm, known as The Hidden Betrayal, was, appropriately enough, hidden away on the 3 layer of Pandemonium, Phlegethon. No one who had seen it ever returned to tell of it, though it was said to be chillingly dark and endlessly dripping with foul water.

History
Diirinka was thought to be the son between Moradin and Berronar Truesilver as well as the brother to Abbathor, Clangeddin Silverbeard, Sharindlar, Vergadain, Thard Harr, Gorm Gulthyn, Marthammor Duin, Dugmaren Brightmantle, Laduguer and Diinkarazan. He was Diinkarazan's twin.

He was banished by his father alongside his twin brother, though it wasn't clear for what.

Interestingly, worship of entities called Diirinka and Diinkarazan existed in Old Shanatar.
