Word is going round Al Kharid that a monk has arrived and is looking for the adventurer who saved Varrock from Delrith. A group of dark wizards is planning to set another demon loose on the world, and the only way to foil their plot is from within! And this time it's no minor demon like Delrith, but a demon-lord with great magical powers. Take up an old sword, dress to impress an evil wizard, and discover forbidden demon-lore under the Shadow of the Storm.

This quest features further expansion to the Demon Slayer and Golem storylines and some very unique characters to meet along the way.
