Nexus Arrangement
From Lexicanum
The Nexus Arrangement is a Necron Artefact. In many ways it resembles the Resurrection Orb as it too is an orb which seems to be containing the baleful green energy used by Necrons. The object was found by the Dark Apostle Jarulek and his First Acolyte Marduk. The object is revealed to be able to create a stasis field of sorts around an undetermined amount of space, presumably blanketing a planet in it's effects. This stasis field only repels Warp Travel to and around the area of projection, literally crippling the area from far-away aid and keeping the wielder of the artefact free of reprisal while they wreak havoc on the planet below.1
The way to work this dreaded device is still unknown by the Word Bearers, a captured tech-magos of the Adeptus Mechanicus by the name of Darioq was captured along with many of his "brain hemispheres" that contain an undetermined amount of information gathered by Darioq. The Word Bearers are currently using the tech-magos on a seemingly unsuccessful drive to unlock the secrets of the arcane object, if the object is indeed unlocked, the very safety of Holy Terra would be at stake and surely drive another Black Crusade from the Eye of Terror into Imperial space.
