What race best fills this role? I'm mostly looking for someone who does this in a Planescape-style setting. Neogi kinda do this, but they're a little too specialized for what I'm looking for. Ditto night hags.
What I really want is generic merchants who ply the Etherial and Astral Planes, exchanging goods between the Primes, the Elemental Planes, and possibly (though not necessarily) the Outer Planes. I can't think of any race that does this off the top of my head, so if someone could point me in the right direction, I'd much appreciate it.
EDIT: Oops! I know about the Mercane, and I really want a race more focused on commodities and such, rather than magic. I'll also admit, I'm not crazy about a race of people who are just humans painted blue. ;p Any other traditional options out there?
