A companion to Dorastor: Land of Doom, this book adds 7 evil and/or chaotic cults for Glorantha (including two never before published), new rules for disease, extensive details on the chaos (?) god Gbaji/Nysalor, and other chaotic unpleasantness. Much of the material was reprinted from the classic supplement Cults of Terror, with all cults updated to the RQ3 rules.
From the back cover: "LORDS OF TERROR is a RuneQuest Glorantha campaign supplement. Complete cult descriptions of seven chaotic cults (Primal Chaos, Malia, Bagog, Thed, Krjalk, Pocharngo and Krarsht) are illustrated through passages from "The Reminisces of Paulis Longvale" an epic saga of treachery, horror, and heroism in the great war between the Orlanthi and the chaotic minions of Ralzakark, enigmatic sovereign of Dorastor, the Land of Doom. This companion volume to DORASTOR: LAND OF DOOM is an essential reference for all Gloranthan campaigns."
