Biography
Y'golonac is the God of Depravity and Perversion, a Great Old One who was imprisoned behind a brick wall in an unknown region. In the song, Y'golonac is served by "blind creatures of darkness" and longs to be released from his imprisonment. Much like the Outer God Nyarlathotep, Y'golonac has a full understanding of human morality as he has the ability to understand any perversion and carnality that any sapient being can think of.

While Nyarlathotep is a vile god, Y'golonac was arguably more so as he also had the tendency of devouring his followers to satiate his perverse hunger. In the song, unnamed monks summon Y'golonac to the earthly realm and he takes possession of their bodies.

The goal of Y'golonac is to escape his imprisonment so he could once again walk freely among humans." In Ramsey Campbell's contributions to the Cthulhu Mythos revolving around the Severn Valley Region, Y'golonac would try to have his victims read a chapter of the Revelation of Gla'aki bearing his name. When summoned, it would ask the summoner to be his priest. If not, they are devoured.

In his self-entitled song, Y'golonac takes possession of the monks in preparation for the arrival of Shub-Niggurath.
