Ankh Triarch

The Ankh of the Triarch, ancient symbol of the Necron Empire

A Gauss Bisector Field is a Necron defensive technology employed by Tomb Citadel complexes often known as a "City of the Dead" by the forces of the Imperium. Utilising power from a multitude of Power Crucibles, a City of the Dead is able to project a vast defensive barrier formed of flickering green gauss energy around its borders.

Any trespasser or assaulting enemy foolish enough to step through the barrier is swiftly reduced to smoking chunks of flesh. The strength of a Gauss Bisector Field against passing enemies is proportional to the number of active Power Crucibles powering it, as it is able to rip apart armoured vehicles at full power.
