My own attempt is a deliberate effort to go back to the few scant
pieces of canon we do have and build directly on them, rather than
trying to incorporate other people’s fan material (the Sunela Coast, for
example) or material that isn’t quite based in Oerth, but has, from
time to time, been made to fit therein (Hitaxia, Momboddo, etc. from the
Sagard the Barbarian books).
What I did use were Gary Gyagx’s Gord the Rogue
books which, although lacking in detail, at least gives some names of
the nations surrounding the Sea of Dust, and thus at least a place to
start. That, plus the map and one-page description in Dragon Annual #1,
were my chief sources (although the upper-right corner of the map is
based on material from The Scarlet Brotherhood by TSR). I’m also
trying for an interpretation of oriental culture different than that
presented in Kara-Tur (which ain’t going to be easy). Thus, my take is
going to be a little bit different than that of others over the years,
but, hey; it’s all mostly non-canon anyway, so why not make it my own?
Also, please take a minute to check out the Adventures Dark and Deep Kickstarter campaign. Help make the ADD rules supplement, suitable for use with all 1E-compatible games, a reality!
