Brethren's Ritual Sacrifice Red Light

Crimson-hued energy field used by Mandragora’s forces to manipulate spatial reality within the rock carving’s illusions. The light transports figures through Xoanon’s psychic deceptions, compelling sudden displacement without physical movement. When deployed, it envelops victims in a seamless sheet before their forced relocation, leaving behind only scorched metallic residue. Leela witnesses its lethal efficiency when it annihilates an armoured explorer mid-transit.
