One of Hrinori's twin worlds, Lor'quhan is a toxic wasteland where only the hardiest and most adapted creatures can hope to survive. Toxic steam vents hurl fumes into the air as a sickly cloud lays across the land. A perfect location for Sku'byss and his will, Lor'quhan is the home of the Heart of Corruption. Most of the life on the planet are toxic plants and ferns that grow near the hot-water basins.
The Silent One created the Plague Amoeboid, modifying them from the void amoeba, to live on this planet.
