Nustukh are creatures known to inhabit the Spirit Plane, mentioned only by Gorajo skinweavers. They are described as being as big as three floors of Daemonheim, and they hold great significance to the Gorajo people, as they believe that they are reincarnations of their greatest leaders. 
- ^ Skinweaver, "Daemonheim", RuneScape. "Naabe, let me tell you something. When I was a few years younger than I am now, I helped to heal a nustukh: a creature as big as three floors of this place. The nustukh do not benefit the gorajo in any way, but they are the reincarnations of our greatest leaders. They have great significance to our people. This nustukh was ravaged by a corruption that ate at every one of its organs. A skinweaver was required to crawl in through an open lesion and heal it: I volunteered immediately. I spent two weeks inside. I cannot help but be reminded of the nustukh in Daemonheim. The dungeons are as rank and unwholesome, and I feel that my powers are just as ineffective inside."
