Ceti IV, was an uninhabited world in sector 85 by 4 by 20. In 2267, Ceti IV was the site of an IPX dig lead by Max Eilerson. During the course of which they discovered a large underground city, abandoned some 10,000 years previous. Following the Drakh attack of Earth, the EAS Persephone tracked and shot down a Drakh cruiser over Ceti IV before being destroyed. Shortly afterwards the Excalibur arrived to secure the site and pick up the IPX crew.
