Sorry its so late, I have been suffering with the flu for weeks...
This world was a random world rolled to fill in a subsector for my campaign, but its Law-level was just stupid so I had to add it here.
Unnamed Experimental World
A89A7CG-7 (includes Gas giant plus Navy, Scout, TAS and Imperial bases, no other factions than main gov)
This is a Waterworld planet that is the same size as Terra and even has a 1.0 surface gravity. However outside of the atmosphere processed arcologies dotted on the world, the atmosphere is dense and tainted, requiring a filter to venture on the Outside seas.
The surface is almost entirely water so the hundreds of millions of people on the planet survive in a number of "Island-Arcologies" that float seperately on the world, each Island holding a handful million people in a small amount of space.
A single government reigns over the Islands, a charismatic oligarchy. Within each Island, a single member of the ruling "Council" resides and runs their Island. All Council members are in contact with each other and so each Island is identical to each other.
The Council has set a contraband on weaponry to a near paranoid level. Any spaceship wishing to pass Highport will be searched for weaponry and criminals (weapon-carriers) will face Imprisonment, though those who are lucky may just face Exile instead.
Those who carry concealable weapons or worse (as dictated by Law Level contraband table in the Core) generally get a Death sentence. The Death sentence is also handed out to crimes more serious than assault, itself getting either life imprisonment or the death penalty depending on circumstance.
This means destruction of property always gets a Death sentence, meaning even if a small child breaks a window playing a ballgame, they are immediately arrested and executed.
The Council enforce crime with deadly seriousness and on top of that hold a monopoly on the Islands atmosphere processors, charging the residents for the ability to live in the Islands or face life on the tainted seas of the Outside. Most are content to live in their crime free bubbles but those who who do not will find even if they survive on the seas and manage to find another of roughly a hundred Islands on the world, their new home will be exactly like the last one.
Technology on-world is a rough match to Terra of the 1980s and filters are available for those who can afford them. There is also a strong Imperial presence of bases near the world's Highport (there is no Lowport).
This is due to the planet being an Imperial experiment to try and quell violence and political enemies to the Empire. At this world's colonisation, political activists were shipped to the planet by the Imperial Navy who protected them from "Pirate attacks", in reality Imperial sent mercenaries, and with the Navy's protection ingrained into the populace as their guardians, it is these Naval men and their descendants who body the Council, as charismatic messiahs who guard the masses from the horrors and violence of the Outside.
