A hyper-grid intrusion[1] (or gridfire) is the channelling of the energy grid into real space. It has a blindingly white appearance.[2]

A similar effect may be achieved by crash-stopping from high speeds while using hyperspace propulsion.[3]


By the Idiran-Culture War, both the Culture and the Idiran Empire had sufficient expertise with the grid to form gridfire.[2]

Novalevel gridfire was used by the GSV Eschatologist to destroy Vavatch Orbital during the Idiran-Culture War.[2]

The Dra'Azon used a weapon resembling gridfire to enforce the Quiet Barrier around a Planet of the Dead.[4]

Gridfire was not witnessed in the Milky Way for at least 500 years after the Idiran-Culture War.[3]
