The Cave City on Rennokk is little more than a rumor. The explorer Reidi Artom reported trying to reach a cave on Rennokk, but was chased off by a worm-like lava creature c. 232 BBY. Another group of explorers returned about a century later and found a city of interconnected metal buildings, but they were also chased by the lava worm. Only one of the explorers survived. His accounts have been called into question, as he was often drunk when he told the story, and his embellishments kept growing over time.
