Here's a revised/expanded version (since there's interest):
Draecis, the Tortuga of Space
- free port, one city on the rock (or gravity well, or planet, or whatever you want to call it)
- governed, if it can be so called, by a council of pirate captains
- haven for pirates, smugglers, mercenaries, assassins and traders looking to avoid tariffs
- slave trade encouraged, no real laws or enforcement as such on Draecis; those in charge of certain areas (Port, the Block, the Arena) are treated as ship captains, total masters of their domain
- important parts of town:
Port—Obviously the place where ships land. The Port Authority’s word is law when it comes to approaches, landings, and take-offs because captains risk themselves, their crews, their ships, and those of others if they don’t listen. Thus, the port authority has several gunboats and boarding parties in orbit and in atmosphere at its disposal.
The Block—The slave auction block. Sellers rent pens and are responsible for board, the rent comes out of the final price the slave brings. All slaves are auctioned by the Block Master (10% fee). Slaves in pens may wear clothing, but those on the block are stripped so buyers can see everything. Slaves must wear leather or metal collars bearing a ring for a leash and their owner’s mark. Slaves lacking this collar are assumed to be free (wo-)men.
The Arena—Here slaves, and occasionally free beings, fight for sport. At random intervals, the Arena Master may hold a Maze Game, in which the arena floor is turned into a maze and a set number of slaves enter. The first slave to reach the center wins his/her freedom. Any slaves who don’t reach the center but survives his/her competitors and any creatures the Arena Master introduces are shot . . . only one gladiator leaves a Maze Game alive. Most games are to submission or death, although creature/beast games are popular and even some sex games are held (either two combatants trying to strip each other, etc. or female slaves being taken by other slaves or creatures; the latter often being used as an intermission between combat bouts when it occurs).
Market—The partially open air place where anything and everything in the galaxy can be bought, tax and tariff free. Haggling is strongly encouraged and most sellers have one or more bodyguards. Money changers also set up shop here, although barter is acceptable to many sellers.
Council House—Sacrosanct place when Council is not in session (Council only meets when 5+ members are in port).
Street of the Gods—Temples, churches, mosques, places of worship for every faith and deity in the known universe are on this street, whether tiny little shrines or massive edifices, pirates being superstitious folk after all.
Mage Quarter—Most of the reputable spellcasting businessbeings set up shop and live here. A number of psis moved in too. Generally treated with considerable respect and a bit of awe by even the most hardened pirates, smugglers, and mercs.
Punishment Square—An open air area filled with stocks. Slaves, problematic crew members, captains who flout the Council, and others can all be brought here for public humiliation. Some slave owners bring their property here to be punished, humiliated, and even used by the public (so long as the slave is not removed from the stocks). Fruit and vegetable sellers routinely hawk their rotten wares to the crowds here. According to custom, free persons brought to the Square cannot seek retribution for anything done to them by the crowd, within reason (such as jokes, mockery, or being hit with rotten fruit).
Earth-exists in the setting, alongside lots of other worlds, several nations, and possibly unlimited species. As far as tech, anything could go within reason—sentient androids, sentient robots, beam weapons, genetic engineered species, nanotech/mods, cyberware, etc. Even different STL/FTL technologies by nation/species. Add in magic and other possibilities open up as well. Even so, FTL flying planets are probably excessive (despite Larry Niven).
