'''Distance to Known Landmark''': Closest is Agurtha Colony, three days out at warp 6. Avronis is less than six days away from the far border of Eryscyne territory, but only if one can successfully navigate the nebula. It is easy to reach with slipstream drive.
'''Nearby Locations of Interest''': There is a Romulan security outpost at the edge of the nebula that monitors anything that might come out of the nebula. The outpost is labeled on star charts as ‘R146.’ It is a manned listening station with a small crew compliment. The outpost orbits a stationary planetoid outside the nebula. It is an older design that is in need
to upgrades and repairs, but still holds defensive and offensive capabilities, including a half dozen small fighter/scout ships that can be called to action if the need arises.
Avronis V has one (unnamed) moon, it is glaciated and without atmosphere. There is an environmentally-domed Romulan moon base on this sattelite. There are no other space stations in the system or surrounding area
After the explosion of the Hobus Star, the Romulan Empire officially halted the dumping of antimatter waste as a show of political goodwill. This was most certainly done to get aid from outside governments, including the Federation. In reality, antimatter dumping only halted on the planets that were close enough to Federation space to be monitored. As Avronis is on the far side of Romulan territory, the policy has always been ‘we don’t care; don’t get caught.’
