Pegasus system strange object

[cursor]

You need to be told about the portals before they work but then you can just use them as many times as you like (or until you land in a huge ambush that kills you lol.) I tried searching for them as soon as i could in a new game but it didnt work. The npcs say you can randomly die but that never hapenned? It just seems to teleport you randomly like if i reload then sometimes it sends me somewhere else
