Soul Master

A boss in the Soul Sanctum. The Soul Master was the head of the Soul Sanctum. He hoarded soul hoping to stave off Hallownest's affliction, but eventually became intoxicated by its power.

Hunter's comments
"The bugs of Hallownest tried all kinds of rituals and prayers to rid themselves of the infection. But to no avail! Perhaps the infection came from somewhere deep inside of them that they could not escape."
