The Kharvashark Ruins were a location on the southern hemisphere of the planet Vrant Tarnum, in the Stygmarn system. Long before the High Republic Era, members of the Elders of the Path hid half of an ancient relic in a cave on the ruins' outskirts. Elder Tromak later told Krix Kamerat the location of the relic in order to keep the information safe, only for Kamerat to reveal the information to the Eye of the Nihil, Marchion Ro.
Acquiring the artifact, Ro then established a Nihil outpost in the ruins, which he placed under Kamerat's command. During his investigation of the death of Loden Greatstorm, Jedi investigator Emerick Caphtor and a group of troopers fought Nihil stragglers at the ruins. Caphtor linked carvings at the ruins to a nursery rhyme he recalled from his childhood, further complicating the investigation.
