Morbollon Mesa was a mesa that was located on the planet Skarpos. In 1032 BBY, Skarpos was captured by the forces of the Sith Lord Odion and Odionite forces were stationed on the outcrop. About a day later, the rival Sith Lord Malakite attacked Skarpos with his mutant forces and attempted to seize the mesa.
It contained a cave which held the Helm of Ieldis, an ancient Sith artifact constructed by the Sith Lord Ieldis prior to the Great Hyperspace War.
