Interstellar Survey Corps

The Interstellar Survey Corps were the predecessors of the Imperial Survey Corps, and worked for the Galactic Republic. One of their four man ships landed on an unknown jungle planet which contained the Dark Side pyramids, though all crewmembers were killed by the Dark Side wraiths and their spirits were trapped in the Altar of the Dark Side. It was from these members that Master Zik'tath learned to understand and speak Basic.
