The Demonic Ruins is a location in level 40+ Wilderness. It is a popular place for players to kill Greater Demons, as it is one of the only viable locations from which it is efficient to kill and bank them. Four broken pillar scenery pieces can be found within some ruined and incomplete walls here.
There is an inaccessible area known among players as Nature-Rune Isle, which contains two different spawns of Nature-Runes. Only one of these stacks may be telegrabbed, which grants 4 runes. They can otherwise not be accessed.
