Pariah Nexus is not absolute

• 9th Ed Codex [Necron]:

"In the case of many - though by no means all - he has succeeded, for the Silent King's scheme is a master stroke. By employing arrays of immense, negatively polarised noctilith pylons, he seeks to create zones that Humanity - in their dawning terror and ignorance - have christened Pariah Nexus. Each of these regions span interstellar gulfs, their malign energies radiating out through the webs of pylons from one world to the next, and blanketing swathes of the galaxy in a shroud of soul-crushing energies.

Where the cyclopean pylons rise to the skies, entire regions of realspace are cut off from the warp as though by a fractured wall of glass. Though the effect is not absolute, warp travel and translation, astropathic messaging and the manifestation of daemonic or psychic energies become vastly more difficult. Should the scattered nexus sites extend until their fields merge, Szarekh believes that the threat of Chaos could be defeated forevermore. Yet this is but one goal of his insidious plan, for the absolute absence of empyric energies would prove as detrimental to the lesser races as does its current ferocious excess. Living beings within the Pariah Nexus find themselves afflicted with a numbing despair that worsens over time, until eventually they slip into a fugue state and thence into irreversible soul-death. This fate leaves their physical forms mindless yet still alive - the perfect vessels for experimentation into the reversal of biotransference. Through his grand scheme, and with the Technomandrites' aid, the last Silent King seeks to provide his people with the means to reverse the damnation he brought upon them, and in doing so unite the Necrons that they might defeat those foes that endure to reclaim the galaxy at last."
