Home base of "King" Hopper Morrison and his Extractors, The Rack and the nearby planet of Pain are small ugly worlds, a combination of slum and pirate Kingdom rolled together. One of Morrison's raiding parties ended up on The Rack and were foraging for anything of value when they stumbled across a buried Star League bunker complete with mothballed BattleMechs. Morrison has since used these Mechs to build his little army into a serious threat. Over the years, the Extractor's have taken thousands of slaves to run a digging operation to dredge off the side of a mountain to see if there is any more Star League tech stored there. Even then, the most believable estimates can only narrow down the combined population of Pain and The Rack to between fifteen and twenty thousand, half of which are slaves.
The world itself has an extremely jagged rock formation, with very few places to even land a DropShip. Obsidian and all sorts of metallic and radioactive ores make up these rocks, and combined with the weather, plays hell with sensors and communications. Back in the days of the Star League there was a weather control system on the planet. Without it, the planet is perpetually covered with rainstorms in some areas, with major thunder and lightning activity. What little light filters through turns the water-laden clouds a sick purple hue.
[3059] Tired of Morrison's raids, the Rim Collection sent the mercenary unit Able's Ace's, effectively it's standing military force, to rid them of the menace of the "King" Hopper Morrison and his Extractor's. Large numbers of his troops were destroyed, though Morrison himself escaped. The Ace's further weakened his power base by freeing all the slave laborers, and destroying the expensive dredging and pumping equipment.
