Ugudenk is a demon lord, in the Dungeons & Dragons roleplaying game.

Publication history[edit]

Ugudenk was first mentioned in the article "Demonomicon of Iggwilv: Fraz-Urb'luu" in Dragon #333 (July 2005), by James Jacobs.[1] Ugudenk received further details in third edition in Fiendish Codex I: Hordes of the Abyss (2006).[2] Ugudenk received a full description in the "Demonomicon of Iggwilv: Apocrypha" edition in Dragon #359 (2007).[3]

Ugudenk received further description in the fourth edition book Demonomicon (2010).[4]


Ugudenk, the Squirming King, is an obyrith Abyssal lord of worms and hungry parasites.


He often burrows into Hollow's Heart, the layer of Fraz-Urb'luu, and while the latter lord was imprisoned he claimed a portion - now called the Spiral of Ugudenk - as his own, infesting it with writhing minions. The spiraling cavern in the center winds all the way to the Writhing Realm itself, and Fraz-Urb'luu has thus far been unable to destroy it.


Ugudenk rules a layer called the Writhing Realm, catalogued as the 177th tier of the Abyss.
