The peteran wormhole is a natural wormhole in the Peteran system. It was first discovered here when ships entered they noticed that the wormhole is stable and exits in the Flerash system over 870 Ly away, this system was not explored at the time, we didn't even know how many planets it had.
First: the entrance in the peteran system with a ship just flying through it (causing the yellow light).
