The Grumani temple chamber on Skarpos The Grumani temple chamber, a structure built by the religious order known as the Grumani Hierophants, was situated inside the Morbollon Mesa on the planet Skarpos. Before the time of the Republic Dark Age, it served as a hiding place for the Helm of Ieldis, an ancient Sith artifact. This artifact, created by the Sith Lord Ieldis, possessed the ability to drive any sentient being into a state of murderous rage.
During the year 1038 BBY, Aron and Mercia Holt came across the chamber while undertaking their quest to find the Helm. In order to prevent the Sith from obtaining the Helm, they used explosives to destroy the chamber, resulting in their own deaths. Prior to their demise, they created a holorecording that explained the reasons behind their actions. However, the Helm survived the explosion due to its dark side powers. Odion, a Sith Lord, later recovered it in 1032 BBY. He attempted to use the Helm to trigger a galactic apocalypse fueled by the Force, but his plans were foiled by Kerra Holt, a Jedi Knight, and her former general, Beld Yulan.
