Riyl Shades or Riyl Shadows lurk behind the steel door in the Mort'tonshade catacombs dungeon. They initially appear as dark reddish moving shadows on the ground and then rise from the depths to attack or retaliate. On occasion they have also been known to leave their catacombs to attack trekkers and ramblers in the town above their dark burial place. Their remains can be with cremated with willow or higher pyre logs. The Salve amulet and Salve Amulet (e) work well on this shade which is very useful if shades are assigned for a slayer task.
In the Temple Trekking, the monsters are called shadows, while in Mort'ton they are called shades.
