Weird that they always seem to keep them in orbit around stars. Seems like prosecuting the Idiran War would have been impossible for the Idirans if they could not find the orbitals.
They probably can’t produce enough AM to power them autonomously, so still rely on stellar radiation. More importantly, it’s kind of fun to have a large star in the sky.
Any Mind that couldn't cobble up a perfect sun simulation invisible to the Idirans would be a disgrace.
