Thinking on "Your Sector, Your Problem" (SHIELD/Stargate Command but responsible for a sector of inhabited alien worlds) in particular in the light of Uncanny Spheres MEGACORP: The Evil Mothership Campaign - why not just use that?

Uncanny Spheres portrays the dark mirror version of Mothership, scheming executives within the iconic megacorporations of that setting - and there is a ton of material there that I think I could wrangle but the 'close, but not quite' sense I get is really helpful to clarify what I am trying to get at with Your Sector, Your Problem.

The high-level pitch in 'DIO - Cosmic Defense Brigade' was "you are responsible for holding down a sector your corporation has newly acquired protectorship of and have a scarce amount of Sector Defense Assets of varying levels of effectiveness and you have to deal with all the problems that come across your desk with those."
The key difference with MEGACORP as I think about it is that even though you are representing a very large entity, an interstellar megacorp, the problems you are dealing with are greater still, so your margin for the kind of back-stabbing and internal politics that MEGACORP foregrounds is less. Not zero, but less. YSYP is like domain management on a dangerous frontier, with potentially hostile residents and unknown buried problems within your realm.

My vision for the setting is a Banksian one or "portal fantasy in spaaaace" - lots of aliens out there, not necessarily all hostile but certainly humans are only small fish in what has turned out to be a very, very big, very inhabited pond.

Inspired by the planetary hexmap by Riles we have here an aqua planet with space-factions, deep-sea mines and aquatic residents. This is the 'get it out the door' ashcan, as baked as I can get it with time constraints of travel. List of things I would have improved in the land of infinite time at the bottom.

The Planet
Humans have come to Planet 44E chasing rich metal nodules on the floor of the planet-spanning ocean. The colonists arrived and have been busy, regularly buying in shipments of gear paid in hard galactic currency but only a trickle of export product is leaving - the miners are close-lipped about their route.

White Corp is losing its mind as their investments hemorrhage cash and point the finger at the Black Coalition presence - they must be smuggling! Avoiding export taxes! Blue Navy has been called in but are failing to find any such regular smuggling run despite significant armed and stealthed Black Coalition transport capability. Things appear stale-mated, with a lot of fuel burnt and sensor sweeps. Ripe terrain for some enterprising mercenaries.
