Traditional Name: Maltharin
Maltharin I, usually just called Maltharin like the system, is a former Klingon mining world on the fringes of Klingon space, approximately 20 light years from Cestus III in sector R21 of the Beta Quadrant. After strip mining the planet of its most valuable resources during the 23rd Century, the Klingons abandoned the planet. They did, however, leave behind the mining and export infrastructure and the planet has since come to be home to smugglers and other criminal elements, as well as desperate prospectors following rumors of untapped veins of valuable minerals missed by the Klingons. The name Maltharin is a corruption of the Klingon Empire's official status for the system, malja'tlhIl-rIn, literally "mineral business finished".
The planet was once Class M but is now considered Class L. Industrial waste from decades of Klingon strip mining has poisoned the biosphere, leaving stretches of wasteland between polluted seas and lakes. The land is completely barren, dotted with the scars of open pit mines. There are also large junkyards as well as scattered small settlements. The atmosphere is heavy with carbon dioxide, and also contains radioactive particles carried from the open mines across the planet by the winds. This makes it difficult to use transporters, and most visitors land in ships and shuttles. There is one major spaceport that serves as the primary trading hub, but smugglers and other criminals have no problem landing out in the wilderness when they want their arrival to attract less attention.
Maltharin is technically still a Klingon world, however since the Klingons abandoned the world and the system sits on the frontier relatively far from anywhere else of note, the Empire mostly ignores it. The entire system is dotted with bases belonging to criminal syndicates, paramilitary groups, rogue factions of several governments, and assorted other groups, all taking advantage of the multiple asteroid belts and the numerous moons of the system's five gas giant planets. Peace between all these factions is maintained by a complex network of agreements and alliances, policed by the more powerful groups with a presence in the system.
The primary settlement on Maltharin is called Far Reach and was the main spaceport the Klingons used to ship material off planet. It is also the closest thing the planet can be said to have as a capital city and central government. The scattered other settlements are few and far between and are small enough to be self-governing. Far Reach contains landing and docking areas and the facilities to support them, as well as amenities for visitors. The planetary population varies wildly and is predominantly transient. Just about every species in the Alpha and Beta Quadrants has been represented on Maltharin at some point in time or other, from Orion smugglers to Naussican pirates, Ferengi traders to Pakled scavengers, rogue Klingons, Romulan spies, Tellarite miners, Andorian mercenaries, former Maquis, and more. Far Reach is currently overseen by a "city council" made up of representatives from the major players in the system, with security maintained by a well-paid militia.
