The core of the Psychic Scourge is a hand-held device that is known as the Power Source which drew energy from the Warp. In truth, it is a [[Necron]] device that can either amplify or nullify the powers of the Warp depending on its alignment.{{Fn|2b}} Inquisitor Drogan believed direct handling and exposure to the Power Source could lead to corruption. This Power Source served to provide the critical energy requirements of the weapon and needed to be opened within a large structure where it powered a lens that fired into the Orbital Spire to distribute its effects around a world. According to the Inquisitor, improper handling of the Scourge is capable of cracking a world in half and devastating its surface. The audio logs made by Drogan indicated that it functioned by focusing excessive amounts of Warp energy into a selected Xenos races race's specific Warp signature. Thus, in theory, this led to massive injury and haemorrhaging hemorrhaging of the creatures creature's central nervous system and killing them in the process. The effect led to the chosen species heads exploding in a violent manner as a side effect of the process rather than the intended result of the weapons weapon's usage.{{Fn|1}}

This device functions by utilizing the [[Warp]] and designed to target specific [[Xenos]] species through their Warp signature. As a result, it was believed that it is capable of eliminating an entire invading force. Research into the weapon is believed to had been blessed by the [[Inquisition]]. This saw [[Ordo Xenos]] Inquisitor Drogan establish a base on the [[Forge World]] [[Graia]] where he continued his study in secret. The project included the study of various Xenos specimens that were subjected to the effects of the Scourge. This included successful tests conducted on [[Ork]], [[Tau]] and a [[Tyranid]] [[Lictor]] specimen that proved the weapon could be of immense value to the [[Imperium]]. At some unknown point, Inquisitor Drogan's work drew the attention of [[Chaos]] that saw him being killed and becoming a puppet of the [[Chaos Space Marine]] [[Nemeroth]] who intended to use the weapon to break the walls of reality to allow an invasion of Graia. The planet Graia came under attack from an Ork [[Waaagh!]] led by [[Warboss]] [[Grimskull]]. This invasion attracted the rapid deployment of the [[Ultramarines]] [[Chapter]] of the [[Adeptus Astartes]] who arrived to repel the Orks. Their arrival led to the possessed Drogan enlisting [[Space Marine Captain|Captain]] [[Titus (Ultramarines)|Titus]]'s aid in securing his ''"weapon"''. The Ultramarines Captain was reluctantly convinced by the Inquisitor to use the weapon to defeat the Orks and the Psychic Scourge was activated. However, this simply splintered the walls of reality allowing [[Daemons]] and [[The Chosen of Nemeroth]] to invade the world. Titus ultimately was able to destroy the device and defeat NemeorthNemeroth.{{Fn|1}}
