Magic, Spirits, and Mysteries
No one knows what creates a kettem, but legend has it that they form when Half-Winds pick up driftwood, infusing it with their malicious energy. What truth lies in those legends is unclear, but the fact remains that creatures made of wooden debris walk Braided Shore, and that folk call them kettem.
People debate whether kettem are simply energy held together by the Winds or if they are sentient beings. There are enough stories telling of powerful kettem who have been heard speaking the Vellan language to make the latter seem the more probable, and possibly more unsettling, case.
