A large, black pearl inside a shell near the Landwalker's Bubble. When smeared with Tanyenn and a few drops of blood, the pearl becomes a magical Golden Pearl which, when eaten, grants the ability to understand the language of the Maerum.
Not to be confused with the ship from Pirates of the Caribbean: The Curse of the Black Pearl.
Obtained from a shell on the sea bed of Arcadia by the Third City of the Maerum.
