An Exile Cannon is a powerful and arcane Necron weapon that can be used as a convenient method for banishing large amounts of unwanted debris, machinery and failed experiments from Tomb Worlds and battlefields into a pocket dimension outside of the normal space-time continuum. However, these arcane ray projectors can also just as easily unleash their energy beams to blast and banish foes, armoured vehicles, and alien creatures to a long and horrifying death from starvation by casting them into other dimensional realms beyond the material universe. The Exile Cannon uses technologies similar to those employed by the smaller Transdimensional Beamer, and is a Canoptek Tomb Sentinel's primary weapon.
