In the "Dungeons & Dragons" roleplaying game, Ilsensine is the patron deity of illithids (also known as mind flayers). While not the creator of illithids, Ilsensine sees mind flayers as the entities most worthy of dominating the universe. Ilsensine is obsessed with gathering knowledge of all varieties, and its ganglia stretch to every corner of existence, tapping into all the knowledge of the universe. The Symbol of Ilsensine is an illithid's head clutching the world in its tentacles.

Description

Ilsensine appears as an enormous emerald-green brain trailing thousands of nerve ganglions off into the distance. It is made of the brains of all the illithids who have died.

Relationships

Ilsensine cursed the derro god Diinkarazan and seeks vengeance against Diirinka, who successfully stole from it. It was formerly served by the illithid god Maanzecorian, who was recently killed by Orcus.

Ilsensine is an enemy of Lolth and Laduguer, but is allied with Kiaransalee.

Realm

In the standard "Greyhawk" setting, Ilsensine dwells in a series of caverns beneath the Dwarven Mountain in the Outlands called the "Caverns of Thought", along with a vast army of mind-controlled thralls. This realm is intertwined with that of Gzemnid, and stretches near the gate-town of Glorium.

Dogma

Worshippers

Ilsensine is served by illithids, cranium rats, and eaters of knowledge.
