My money's on Teladi somehow.
- Maelstrom bordered Teladi space in the past.
- Maelstrom has Xenon stations that look like spiky perversions of Teladi stations in FoO.
- Teladi in FoO don't mind attaching asteroids to their stations.
...having said that, the glowing bits remind me of Otas
...but I probably like even more the idea it could be Split making a ship with their F/F device that also looks a bit like a Xenon capital
...but then Xenon seem to they have an unusual interest in water and that sphere looks water-holder-like! Garghhhhh !!!!
