The Shadow Realm is a mysterious location in Gielinor. Although it seems to be part of the world itself, it in some ways resembles another dimension. Players are able to see into it with the Ring of visibility, and become part of it with the Ghostly robes.
The Shadow Realm is featured in the The General's Shadow miniquest. During the miniquest, it is said that the Shadow Realm is a dimension in which the Mahjarrat have great control over, with the Mahjarrat General Khazard and his followers currently in the realm preparing for the next Ritual of Rejuvenation. General Khazard is confused when he sees the player walking in the Shadow Realm with the assistance of the Ghostly robes, claiming that normally only dead and Mahjarrat can do so.
Sliske is mentioned by Zemouregal, Azzanadra and Wahisietel as being particularly skilled at reaching into the Shadow Realm, although Wahisietel claims that Sliske was better at manipulating the Shadow Realm of Freneskae.
