The Stygmarn system was a star system which contained the planet Vrant Tarnum. Half of an ancient relic guarded by the Elders of the Path was hidden in a cave on the planet's southern hemisphere, near the Kharvashark Ruins. Elder Tromak confided the location of the artifact to Krix Kamerat when they were in danger from the Nihil, whose leader Marchion Ro sought the relic out.
