The Dark World is in danger, for the Veil protecting it is vulnerable. A war is brewing among the Underfolk rebels, the fierce Icecarls, and a hidden, shadowy evil that is just now letting itself be known. As shadows rage, ancient spells return, illusion reigns, and corruption threatens, the search for hope is the bravest quest. It is up to two young heroes, Tal and Milla, to fend off their own darkness in order to save their world from destruction. There is mystery, magic, and imagination at work here. And the Seventh Tower is the key to it all.
