The Realm War was a conflict between the chief polity of the Gelt species and the Compact beginning in 429 IE with the Gelt Incursion brokered by the Laral Family. The Sovereign of the Realm and His advisors and successors expressed deep reluctance for a prolonged conflict, but a diplomatic solution proved elusive.
The war heated up in late 429 when the Challenger dropped several fusion and kinetic devices on a Gelt colony. In retaliation, the Realm bombed Krupp, capital of Bromdar, with a dirty fusion device.
