There are currently 22 instances of the Abacean variant of dried slaughterfish in the Narsis section - while I can see this being an expensive import for some wealthy narsis nobles, it seems far too widespread, and even shows up in the fishery, which is supposed to contain fresh fish caught in the Thirr. The use of these items should probably be cut down, and its id should probably reflect its abacean origins to prevent further misuse.
