Our four heroes are sent to Shimmersand to find the lost city of Eboni where the last Queen, Callista, fell before the glittering influence of Laethys, Dragon of Avarice. Now, The Golden Maw Cult, greedy followers of Laethys who wish to free her, have heard of Callista's Crown. Legend has it that when Eboni fell as Laethys was imprisoned, Callista went to her death amid the melting gold and jewels she had hoarded. On her head was her crown of pure Sourcestone...and The Golden Maw wants it to free Laethys. Emaranthe, Ivo, Jaeger, and Jadeth must find the city, find the crown, and stop The Golden Maw's evil plan.
