The Ankh of the Triarch, ancient symbol of the Necron Empire
A Gravity Pulse is a potent gravitic weapon used exclusively by the Necron air defence constructs known as Obelisks.
When activated, the Gravity Pulse allows an Obelisk to manipulate the energies of a minute gravitic singularity contained within it to produce an expanding wall of earth-shakingly powerful force.
If an enemy aircraft is hit by this sphere of gravitic force, it inevitably is smashed aside and severely damaged, often being turned into a plummeting wreck as the pilot loses control of his aircraft.
