Eschatologist was the temporary name of a Culture Ocean-class Systems Vehicle in service during the Idiran-Culture War. The ship took on the name when it was assigned to destroy Vavatch Orbital. At A/4870.986, the GSV Eschatologist broadcast a general warning to all entities near Vavatch announcing the Orbital's scheduled destruction at A/4872.0001. The GSV carried out the act with gridfire and CAM.
