Mount Tantiss
this mountain, located on the planet Wayland, was considered a a forbidden place by both the Psadan and Myneyrsh races. This made it the perfect location for Emperor Palpatine to hide his collection of valuable artifacts and extreme technology, including a cloaking device and the Spaarti cylinders used for cloning. The main purpose of the Mount Tantiss installation was to protect and preserve the new technologies in case of the Emperor's death. To this end, the Emperor placed a Guardian to watch over the installation. Joruus C'baoth later arrived on Wayland and defeated the Guardian, taking control of the Imperial interests there, but was unable to maintain control of the world. In the aftermath of Grand Admiral Thrawn's reign of terror, C'baoth confronted Luke Skywalker and Mara Jade within its living areas. In the battle of light and dark, Luke and Mara defeated the clone Luuke Skywalker and C'baoth, but the release of dark-side energy brought much of the mountain down in a huge explosion. Nearly everything in the storehouse was destroyed, and the mountain itself was shattered. It later collapsed under its own weight, reducing itself to a slope of rocky debris. Some years later, a clan of Noghri established a dukha at the foot of Mount Tantiss, as a reminder of the betrayal their race suffered at the hands of the Empire.
