[Morai]

Here's some more I've thought of:
"Gimli's" instead of "Lowe's". There you can find pracitcal home and cave improvement products. They also have high quality battle axes, and dwarf armor. Gimli's also has the rare Mithril by the brick.

Back to "Old Sharky." I think they would most likely sell staffs and white robes. Probably printed with the logo of the White Hand and the name Old Sharky printed on the sleeve.
