Lore gibberish.

The anchored husks of Karamadi islanders can be found all across the Charcarbi sea. During the time Dokinian, Caihelman, Randish, and other Anurelian traders started making their way around the south of Addakeirn, the sailors would capture some of the Karamadi warriors that would attack them, tie to them to anchors, and drop them into the sea, the way the tribal mainlanders would do to the Karamadi years ago. However, the sailors would also pin the bodies with spears, as the tribals told stories of the Karamadi rising from the depths as zombies to kill and plague the mainlanders.
