Something monumental is brewing over the Harz! Just escaped from hell, a flood of new conflicts is crashing down on the magical community of the Harz. People are disappearing in droves without a trace, and brutal murders are causing horror. Together with their friends, Elisabeth, Theobald, and Sabrina are desperately searching for a way out. Could the quarter-dwarf Svenja possibly help them? Or even the legendary dragon slayer Siegfried? Despite all efforts, the Harz is heading towards an inferno. Ragnarök, the end of the world, is set to occur right at Walpurgis, forcing the heroes into a dramatic decision: all Harzers - including the non-magical ones - must help, or the world as we know it will cease to exist. A spectacular conclusion to the Harz Magic trilogy.
