Shadow in the Warp does effect Necron tech?

• War in the Museum:

"“The magos paused. ‘I advised you not to refurbish the tyrant.’‘It is not the tyrant. Though it may be… involved. There has been a nexus fault. We cannot signal the legion, I cannot transfer”“consciousness, and Flesh-Stealer has awoken.’‘Only the lictor?’ The magos’ eye-lenses rotated in suspicion.

‘Keep staring at me like that, magos, and I’ll stop sending your little research packages to the Mechanicus. Or should I keep sending them, but add a little gift of my own – a jokaero code-virus perhaps?’

‘Lictors are precursor organisms,’ the magos answered, dipping his head. ‘Meant to operate at the limits of the hive mind. It is understandable that one might awaken from even a weak signal.’‘It still should not have broken out of its containment.”

Tyranids project a psychic energy, Trazyn. A shadow in the warp. Especially Hive Fleet Kronos. You artificials can’t feel it, but it disrupts more than psychic patterns. Technology, arcane devices, even languages can come under its effect. And what “remains of my organics tell me that the shadow has fallen on Solemnace."
