Transported to a mysterious island, an Elven princess encounters the mystical Dargonesti and their wondrous castle beneath the sea

During a vicious Elven war, a princess of Qualinost and an elite band of warriors sail forth to rescue their countrymen from the collapsing Ergoth Empire. Their journey goes awry when a strange mist engulfs Princess Vixa's ship and transports them to a phantom island.
When the mist clears, Princess Vixa meets her captors: the fabled Dargonesti. No soul has encountered the Dargonesti or visited their city of pearl marble that rises from the sea floor—and lived to tell the tale. Princess Vixa and her companions meet this race of sea elves, experience a fantastical underwater world, face a foe counted among the legends of Krynn, and accept an impossible mission that will bring them back to the land they call home.
