Abalone is the largest island of the Wavecrest Archipelago, holding the capital of Seahaven, the cities of Gateway, Gullwing and Diver's Joy as well as the Black Temple.

The eastern coast of Abalone was struck during Calibration 779 by a tsunami. The cause of this tsunami is unknown to the general public, but Azizah and Sunset Water along with the Solars of the Wavecrest Archipelago know; it was the result of a geomantic engineering accident that occurred during Pika's work to raise Saigoth back above the waves.
