After being seemingly beaten, Soul Master releases his Desolate Dive spell. The Knight encounters Soul Master at the top of the Soul Sanctum where he ambushes them. However, he was driven to obsession in his quest for immortality, and lost his sanity while trying to get closer to the light that was guiding him in his mind. Unlike the rest of the Kingdom's inhabitants, he and his followers were able to survive the Infection. He had Soul Totems gathered in the Sanctum and drained many unfortunate bugs of their vital energy. Soul Master hoarded Soul and consumed it, eventually gaining new Soul powers. He refused to listen to the Pale King opposing his work, and failed to realise that his own infected mind was influencing him. When the Infection started, he came to the conclusion that Soul, the energy animating bugs and beasts alike, was the solution to cure their mind of this plague. Soul Master is the leader of the Soul Sanctum of Hallownest, which searched for ways to expand the minds of bugs and attain pure focus. Defeating him grants the Desolate Dive Spell. Soul Master is a main boss in Hollow Knight.
