Hope Rock is a large mountain located somewhere in the swamps of Morytania. It does not appear in game, but is instead featured in the Return to Canifis novel as a central plot point. The most noticeable feature of Hope Rock is its large plateau near the top, encompassed on most sides by large mountain walls, and an elaborate cave system that at one point housed over 200 members of the Myreque.
During the novel, it is discovered a band of escapees from Meiyerditch reside at the plateau, along with the infamous Master Peregrim, a Gnome who had gone missing some years prior, after his hot air balloon like contraption broke free of its tether in Varrock and carried him over the River Salve. Using nets made from the Giant Snails that reside nearby, the band of escapees, about 50 in number, had constructed a large net underneath the balloon to carry them westward over the salve. The plan goes ahead, with the balloon nearly ready to take off, when a sudden ambush by the werewolves of Canifis leads to a desperate scramble to get the balloon of the ground. In the midst of fighting a werewolf which had managed to climb on board before the balloon took off, Vanstrom Klause secured himself to a rope, and jumped overboard with his attacker. When on the ground, he severed the remaining mooring line, setting the balloon free, carrying the others with it and ending any hope of his escape as he left to fend of the ravenous wolves.
