I would like to first say that this is not an attempt to gatekeep Aether out of anyone's hands, and that im simply trying to give constructive criticism and use IC logic and not OOC chest-beating for it. And I am not telling anyone they can't have it, but just want to point a couple of things out and leave the overall decision-making to the NTSE and the SM.
Aether is an extremely complex power source and is highly regulated in setting with only a single non-superpower holding it, being origin, and only because they are backed by both yamatai and nepleslia who are the authority of the sector and both regulate and restrict aether technology.
Its so complex that only Yamatai has yet been able to successfully miniaturize it technology-wise. And Nepleslia has only recently been able to make their own Aether-powered batteries. It's the kind of tech that requires the sheer R&D backing of a superpower like Yamatai or Nepleslia to even break ground in understanding how the stuff works, as its not as simple as taking a look inside to see how everything works even if PP did drain their entire budget to make it so.
The technology is also highly regulated by not only Yamatai but also Nepleslia, who i recall PP being rather close to location-wise. And as a mercenary group, even an unaffiliated one, Nepleslia imposes strict laws onto any mercenary force encountered by its forces, vessels, or is even known about. And one of the rules they enforce is that technologies like Aether are restricted from mercenary groups and are subject to immediate seizure.
Military-grade warship hulls and restricted technologies as well are barred from civilian or mercenary groups as well. Meaning the ship PP has would no doubt be discovered while so close to Nepspace as Aether generation leaves a very distinct and easy-to-track signature that when discovered so close to Nepspace would get a taskforce from one of the sectors most powerful navies on PP within hours. And finders keepers salvaging logic doesn't stand when one of the two superpowers takes a stance.
All that said i can only speak for Nepleslia and what would happen IC from them when not if it's found out an unaffiliated mercenary group has restricted technologies and a military-grade warship also containing them. I would recommend PP keep their aether ship secret and simply use it as a one-off trophy and not free aether-tech to retrofit.
