It is a very silly suggestion, don't give it too much importance, but in my personal game the shuluri from Malqanar usually wear as a weapon the tebuje, a weapon from Arms Companion. Some of this weapons are made from the teeth of sharks , and their purpose is more of reaping instead of slahsing. It seems to me that underwater fighting is most useful this kind of weapons. Shark teeth in a subaquatic culture seems nice to me.
Also, it gives the shuluri a little more special details about his way of living/fighting. I like this weapons as chegain, Kynac, that are very integrated in some cultures, they give a cool flavour to the game.
If Terry likes the idea may be it could enter in Emer III, if not, well it isn't important.
