Description
This helm and its associated components are marked with the seal of Stormwind. It was no doubt cast off from an Alliance ship that suffered a similar fate to yours.
Looking closer, this seems far too intricate and sturdy to be everyday diving equipment. Perhaps Nazgrim can make some sense of this...
