Description: Tarnoonga was an ocean-covered planet located in the Arkanis sector.
The seas of Tarnoonga were the homes of giant sea monsters such as the Miridon, who made its nest in the ruins of sunken freighter ships settled atop the undersea mountain ranges. The peaks of many of these mountains stretched upward, breaking the ocean's surface, forming immense natural caverns and grottos.
Some years prior to the Battle of Yavin, the pirate known as Gir Kybo Ren-Cha established a hideaway base inside the depths of one of these tall mountain peaks. His crew horded the purloined treasures from nearby worlds such as Tammuz-an and hid them within private caches inside the mountain tops. Kybo kidnapped Jann Tosh and Jessica Meade, heroes affiliated with Tammuz-an, and brought them to his grotto on Tarnoonga. With the help of the droid team of C-3PO and R2-D2, however, Tosh and Meade were able to escape.
In 4 ABY it was a place of confrontation between Luke Skywalker and S'ybll.
Kybo Ren's base
The pirate captain Gir Kybo Ren-Cha operated out of a base built into an island mountain on Tarnoonga during the early years of the Galactic Empire.
After the pirates were defeated, the base was abandoned until it was taken over by the Galactic Empire for use as an outpost. The Imperials kept an Oskan blood eater at the base, trapped within a pit. Sometime after the Battle of Hoth, Imperials inadvertently brought the mind-witch S'ybll to the outpost. While using her illusions to pose as an Imperial trooper, she drained the life force from all the Imperials at the base. When Rebel scouts, Andur Thorsim and Glaennor arrived at the base in a G9 Rigger-class light freighter to investigate, S'ybll imprisoned them and manipulated them into drawing Luke Skywalker to the base. During the encounter, Skywalker's droid, R2-D2 used a T-65 X-wing starfighter to blast a hole in the structure. The maneuver allowed Skywalker to defeat S'ybll, causing her death.
