Dar Mataan

Dar Mataan is an ecumenopolis moon nominally ruled by the Zekhari. It's one of the most populous planets in the outer rim, and is one of the most dangerous planets in the Galaxy. It is a major hub for intergalactic travel and commerce within Zekharian space and the Outer rim.
Whilst technically within the jurisdiction of Zekharian space and owned by a group of powerful Zekhari warlords, in practice it is controlled by gangs and The Cartel. The Cartel's involvement with Dar Mataan is complicated to say the least, but in general it is an officially sanctioned entity and maintains control over most of the planet's most populous areas.
