Led by Sharinia, a sorceress, the people of Oval-Lath go on an exodus and battle the murderous Sacts. Torkh, Tmara and their friends explore the half-ocean Oval-Lantis; its inhabitants raise many questions, especially if a punitive expedition by Strang is repulsed. Rolauth the CyRis experiences the greatest adventure in Oval-Magis and is introduced to the Book of Wonder'ous Spells. Unfortunately, the LabCreator and the Doom Bringer also appear again. And if that had only been the worst... Kron the Mad and the Helleiter join the Doom Bringer and also receive reinforcement from Noa, a special scientist. What is this mighty devilish Pact of Madness up to?
