Vjun
this planet was located in a remote sector of the galaxy, and was known to the Jedi Order to be a nexus of Dark Side energy. The planet was distinguished by its desolate environment, which was dominated by acid rains and muddy rocks. The human population of Vjun eked out a meager living, with a collection of influential families holding large portions of the usable landmass. What was unusual was that the population of Vjun had a much higher midi-chlorian count, on average, than most other human populations in the galaxy. The ruling families made it their business to understand their counts, and a higher midi-chlorian count was considered a sign of power and prestige. Buildings on Vjun had to be built of heavy stone and dense alloys, but even these materials eventually were eaten away by the acid rains. Some eight years before the onset of the Clone Wars, the planet was swept by a plague of madness that wiped out a huge percentage of the population in just a year. The survivors struggled to exist without many of the necessities, and Vjun was virtually forgotten. It was only later that it was learned that the plague came about as the result of genetic tampering done by the Viscount Malreaux and a group of elitist nobles, who had tried to manipulate the number of midi-chlorians in their cells to achieve more strength and power. It was on this planet, years later, that Darth Vader established a private retreat during the height of the New Order. He built Bast Castle there, and kept Obi-Wan Kenobi's lightsaber in a protected alcove hidden inside. The lightsaber was later recovered by Anakin Solo and Tahiri Veila, along with Tionne, Master Ikrit, and Uldir Lochett. The planet itself was little more than a cloud-shrouded gray ball from orbit, an appearance that changed little when one landed on its surface. The ground was rocky, with very little vegetation. The skies were continually swept by storms, and the average temperature was kept low due to the dense cloud cover.
