So, i have a concept idea and I'd like to try out based loosely on the city of Commoraugh, which is a survival of the fittest den of scum, villainy, debauchery, and warring factions of all types. Basically, take a massive ship, let's say a Universe class, and have it be a derelict controlled by the long isolated and segregated factions of each segment. Some likely candidates would be the Tech Priests, a Ministorum branch (possibly corrupted by centuries and generations of separation..?), maybe some hive of thuggery that makes it's fortune off of chem-shops rigged in the decades of lawlessness, maybe even a Twist-colony that seized the armoury and maybe even led to this disaster befalling the crew, though such a fact would likely be long forgotten.
Essentially, it's a chance for the PCs to seize control of whatever small group of like-minded followers and their little section. You accrue followers, crush opposition, seize assets and otherwise play a faction from the perspective of your character.
I would love to play this, but if nobody would step forward I could make a stab at GMing.
Might hit you up later for more info.
