A male Muun named Larsh Hill worked in finance and belonged to the InterGalactic Banking Clan. Functioning as the Chief Operating Officer for Damask Holdings, he was a close confidant and ally of Hego Damask - the secret identity of the Sith Lord Darth Plagueis. Prior to Hego, he had a similar relationship with Damask's father. After Larsh's death, his son, who would later become the Separatist Council leader San Hill, assumed that role.
Hill had a strong connection with Hego Damask, and he was among the first individuals to encounter him on Muunilinst in 67 BBY. This meeting occurred after the injured Muun had returned from Bal'demnic following the elimination of his Bith Master, Darth Tenebrous. Being a trusted confidant, Hill frequently accompanied Damask on various business endeavors, including a trip to Naboo where Damask Holdings aimed to secure plasma reserves with the assistance of Bon Tapalo and Ars Veruna.
In 52 BBY, Hill received the honor of being inducted into the Order of the Canted Circle. However, this honor turned out to be deadly, as Maladian assassins hired by Pax Teem chose his initiation ceremony as the moment to attack Damask. Within the Fobosi District of Galactic City, Hill, while in the presence of Damask and other members of the Canted Circle, knelt before a Maladian assassin in disguise. The assassin then swung a pendant, which struck Hill's neck, instantly decapitating him. His head rolled several meters away as his hearts failed one after the other.
Hill acted as a paternal figure for Hego Damask. He often expressed concern for the young Muun but was occasionally frustrated by him. While Hill valued business, he sometimes harbored resentment towards certain business partners, such as the Tonith family.
