Here prospectors have discovered vast energy sources sacred to the Eryxian Reptile men. The reptile men have the ability to create invisible structures with the abilities of a Hallucinatory Terrain (pg.23) & Invisibility II (pg.24). These structures are placed on the normal pathways & traffic areas of humans. A large energy crystal is placed as bait & the reptile men wait.

These peoples are found on other planets & are quite adapt at using so called "light envelops" to sail between the stars.
