Tawil at'Umr is an unusual and little-known Great Old One that serves as the physical projection of the Outer God Yog-Sothoth's will and pursues Yog-Sothoth's goals across the dimensions. It is theorised that Tawil at'Umr is little more than the side effect of Yog-Sothoth brushing up against this universe. Tawil at'Umr has vast knowledge about reality.
Tawil at'Umr appears as a cloaked figure of approximately the same shape as and larger size than the observer. Under the cloak, it is revealed as a seething protoplasmic mass capable of taking many shapes, several of which should not be able to exist.
Devotees of Tawil at'Umr typically worship it out of a mistaken impression that worship matters to the avatar. No cult of Tawil at'Umr is known to exist. Most who would venerate it instead worship its true form Yog-Sothoth.
