Slag's Pit

Slag's Pit, often mistakenly referred to as Slag Spit, was a planet in the Ojoster sector of the Outer Rim Territories. It was most known as a "graveyard" for decommissioned starships and the sight of a disastrous Republic defeat during the Clone Wars.

Description
Slag's Pit's surface was dominated by oceans of corrosive acid, and rained the same corrosive material constantly in some parts of the world. Although the atmosphere was breathable by most beings, the acid oceans and rain made it impossible for any permanent settlement except for a species of beetle which came to be known as slagshells, which survived by feeding on dead slagshells and a species of red, moss-like fungus - the only other species who inhabited the world. Slagshells also spit a corrosive material, which softened the fungus for consumption. Both lifeforms were extremely poisonous to Humans, and the spores emitted by the fungus required any sentient - on top of the acidic air - forced any other lifeform to wear specialized equipment.

History
Slag's Pit was discovered c. 200 BBY and immediately became host to an orbital shipyard owned by the Corellian Engineering Corporation. A gravitational anomaly occurred in around 150 BBY, causing most of these shipyards to fall into the planet's surface; hundreds of large vessels, many of which having not even finished construction, fell with it. After the catastrophe became well-known in the media, Slag's Pit, like many other ship graveyards, became a popular attraction for scavengers brave enough to risk the acidic environment. Some of the shipyards remained in orbit and continued operating into the New Republic era. Members of the Rodian Junk Cartel set up a small settlement in a ravine on Slag's Pit, from which they salvaged the surrounding wreckages and sold valuable parts to their allies in Hutt Space. Naastau, a Mandalorian, was sent by the Black Sun to assassinate the Rodian warlord that oversaw the operation on Slag's Pit. After realizing the environment was not survivable, he stayed in his ship and completed his mission by shooting a torpedo into the ravine, causing the network of "houses" built along the ravine's walls to collapse into the acid river below.

During the Clone Wars, a Separatist fleet launched an assault in the Slag's Pit system, engaging with the CEC security ships that protected the shipyards. A fleet of Arquitens-class light cruisers spearheaded by a Venator-class Star Destroyer was sent to the system to defend the remaining shipyards, though failed in their mission as the last four shipyard stations were shot down. A droid army was deployed on Slag's Pit's surface to search the shipyard crash sites, and a Republic battalion - comprised of non-clone soldiers - were deployed in a last ditch effort to salvage victory in the system. For the next month, the battalion was gradually cut down as the Separatists made a makeshift fortress out of one of the crashed shipyards. What remained of the Republic soldiers made one final attempt to defeat the Separatists by sabotaging the fortress with what last explosives they had. As their luck got no better, they were forced to call for evacuation by a Republic fleet that was four systems away. During the early Imperial era, a stormtrooper regiment was deployed to Slag's Pit to eliminate the remaining droids as part of the Reconquest of the Rim, and had much better luck in their mission than those who tried and failed only months earlier. Many of the Republic bodies scattered around the makeshift fortress were recovered by the stormtroopers, though the rest had dissolved into liquid after months of being exposed to acid rain.
