Harbinger of the Storm
Harbinger of the Storm is the title given to a Necron Lord capable of summoning a tremendous storm that jams all communication signals over a very broad area, causing general disarray among enemy forces, and thus granting a large tactical advantage to the Necrons.
A Harbinger is able to fully control the tempest it has summoned from thin air, not only preventing deep strike attacks into Necron lines, but also allowing the Lord to call down devastating lightning strikes that can reduce powerful machinery to mere pieces of junk and obliterate entire squadrons. The only way to quell this mighty tempest is to incapacitate the Harbinger at its centre.
Stormcaller War Cell
The Harbinger is accompanied by a formation known as a Stormcaller War Cell, composed of several Wraiths that guard their master, exploiting the storm's properties to become even more ethereal than usual, providing a nigh-invincible bodyguard for the Harbinger.[1]
