The oceanic races of Krynn are still suffering under the legacy of the dragon overlords and the War of Souls. The difficult job of uniting the fractious sea races falls to the Dargonesti sea elf Apoletta. The long-lived Apoletta is one of the last surviving key figures from the original Dragonlance saga, having first appeared in DRAGONS OF SPRING DAWNING in the Chronicles trilogy. The waters of the oceans are gradually being poisoned. Apoletta and her unlikely allies must not only investigate and defeat a strange new menace hidden deep beneath the waves but face a friend turned foe.
