Which makes me think, would siding with Drifters help us recover illegally occupied by Triglavians territories?
What do exact Drifters need? Corpses? We could feed them corpses of Kybernauts or corpses of those who were hunting them down. Those of us who kept neutral stance to Vigilant Tyrannos, I guess, could try to establish contacts with them with sacrificing raiders who were murdering them.
I think that offering them corpses of their enemies will also allow us to speak to them from position of power instead of some sort of beggars, it will show our merit and excellence in combat against thouse marauders who were diving into their wormholes.
If the operation will be successful, the State and Empire will get a powerful ally in face of Drifters. And if we will be especially persuasive, maybe we could even try to make Vigilant Tyrannos to pledge their allegiance to the State as Ninth Mega.
