The Grave of Scorpius, also known as the Shrine of Scorpius, is found south of West Ardougne in some crumbling ruins atop a hill. Here the Spirit of Scorpius lurks around his gravestone. There are also some ghosts, grave scorpions, and dead trees, as well as thirteen bone spawns. The Shrine has a Celtic cross on it. The Ourania Cave (and Ourania Altar) is found north of the Scorpius Shrine.
The easiest way to access the Scorpius Shrine is to use a ring of dueling to teleport to Castle Wars and run north. Additionaly, players can also teleport to the Khazard Battlefield via the spirit tree and run west.
By talking to Scorpius, players can get an Unholy mould and have their Unholy symbols blessed. A ghostspeak amulet is not needed to talk to Scorpius, but he will only talk to players who have "seen beyond the stars" (finished the Observatory Quest).
