Kaskagarin. (1326 Poonch subsector, Glimmerdrift Reaches... C585988-A)
This is a world with a single major continent. It is rife with black markets and other nefarious goings on. Its the sort of place pirates unload their stolen goods as well as a place that legitimate trade is occurring.
There are numerous off continent "platforms" and operations on islands and atolls where all sorts of nefarious and evil gangster / criminal stuff is going on.
Ruled by an "Emir" (the equivalent of a Baron in terms of
Traveller nobility, it is a stable, if dangerous den of inequity.
The capitol is Raub Tepe and the starport is in Paka Kurau nearby.
Characters I've used in stories there include:
Roland a drug dealer, who got killed in a deal gone bad...
Boss Siyov, who runs a syndicate and owns several night clubs and the like.
Stiglitz, an arms dealer: A short, pudgy, troll-like, balding man with a pointy nose wearing pince-nez glasses and wearing a cheap suit who runs Sepang Import - Export.
The whole is taken in part from the anime
Black Lagoon (which is well worth watching if you haven't)
https://en.wikipedia.org/wiki/Black_Lagoon
In an interview with Otaku USA, Rei Hiroe stated that Black Lagoon was inspired by James Ellroy, John Woo, Quentin Tarantino and Stephen King, as well as hearing about actual piracy cases in the East China Sea in the 1990s.
Rei Hiroe was the writer for this anime.
