A string of southern islands in Le-Wahi inhabited by mutated Rahi, representing the forgotten peripheral geography of Mata Nui.

They're easy to overlook in the grand Bionicle timeline, one of those locations that shows up in encyclopedias and maps but never quite gets a story arc of its own. That absence tells you something: these weren't strategic outposts. They weren't ancient secrets. They were just islands off the coast where the wildlife got weird.

Not every island needed a tournament arc or a hidden prophecy. Some were just there, part of the map, habitat for creatures that existed in the Bionicle world but never directly encountered the Toa or shaped their journey. That's the real strength of world-building: the forgotten places.

The lack of specific detail about their end is telling. They're one of those locations that left the narrative before the narrative ended them, already fading from the geography by the time the island's story wrapped. Bionicle's best locations aren't always the ones with the most page time.
