[Excerpt from a longer banned work on supernatural ritual]
It is said that we should not sully our hands when combating the forces of the Void. My studies have been deemed heretical by my brothers, but the rewards have been invaluable. I have harnessed the same energies employed by the Outsider and his accused followers while avoiding their corruption.
I will prescribe a two-fold method in this text.
Indirection: As the unwholesome powers of the Outsider use living flesh as a conduit, we can avoid being tainted by using the flesh of others instead.
Containment: By using Channels and Barriers we can focus these Void energies in a raw state, shielding them from the perverse perspectives of the Outsider.
