Muunilinst was the third planet in the Muunilinst system and was a lush world of forests and plains. It had a liquid iron core, a strong magnetic field, and was volcanically active throughout its known history. Its shallow oceans contained hundreds of "smokers," conical volcanoes built up by powerful vents in the crust.
One of the wealthiest worlds in the galaxy, Muunilinst was the home of the InterGalactic Banking Clan. The native Muuns turned the world into an immense center of commerce, despite its distance from the Galactic Core.
Gleaming marble edifices dominated the stately cities of Muunilinst. Columns, capitals, volutes, acroteria, and entablatures can be found throughout the Muun architecture. These classical structures would become marred by warfare on rare but devastating occasions.
The tall, gaunt Muuns were famous for their financial acumen, mathematical genius, and greed. Muun children could calculate complex formulas as quickly as most adults of other species. Muuns typically looked at other species as hot-tempered and immature and felt little guilt in exploiting them. They possessed a drive to competition with other races and even among themselves. They also had a fundamental respect for fairness, however, and regarded a contract as almost a sacred trust; they were known to always follow the letter of the law, though often not the spirit. Their society followed a strict caste hierarchy. Higher castes were financiers, lawyers, engineers, and diplomats. Common Muuns rarely left the surface. Upward mobility was limited to the most gifted of common children: they were tested rigorously, and if found worthy, were allowed to enter the higher castes
A skyhook connected Harnaidan with High Port, an orbital city. The Golan space defense platforms defending Muunilinst could be seen from here, as well as a magnificent view of the planet glittering below. Mariunhus was a particularly rich city built around a smoker rich in gold, platinum, and other precious metals. Mariunhus was an example of a "vault-spire," a virtual mountain of wealth, kept safe and secure, which could be mined at a moment's notice to guarantee credit anywhere in the galaxy. Other smokers were known for industrial metals and were known as "mine-spires."
During the Battle of Muunilinst 22 years before the Battle
of Yavin, Obi-Wan Kenobi, Anakin Skywalker, and Voolvif Monn retook the planet for the Republic, but at great cost. The Separatists fought savagely to hold the planet, with waves of battle droids and a special platoon of IG lancer droids led by
bounty hunter Durge. Confederate gun emplacements operated from within the cities, leaving Republic forces no choice but to assault the cities directly. The battle devastated the Muun infrastructure and led the galaxy to the brink of financial ruin. The Republic persevered, and Kenobi was able to capture the Banking Clan leader, San Hill.
After the Empire's defeat at the Battle of Endor,
following the death of Grand Admiral Thrawn, and the loss of the Core worlds to the New Republic, Muunilinst became the financial heart of the shrinking
Empire. Many Imperial officers nicknamed the planet "Moneylend." It remained part of the Imperial Remnant during the New Republic years, protected by two Golan III battle
platforms, defenses which Moff Disra had tried to move to Bastion. Amazingly, but again consistent with their reputation, even while a part of the Imperial Remnant, Muunilinst still became the guarantor of the New Republic credit. This infuriated the Moffs, but they were powerless to move against the IGBC without destabilizing the Imperial credit.
