What Xanndros said. Most of the focus will be on the City of Babylon and the desert around it. (The sand pirate domain with shanty towns and huge ruins.) but you can go anywhere you want. :sun I'd advise against starting off miles away to begin with because you might miss out on bits.

We may well head to Edessa or Actim for a spell as a group once i've wrapped a few things up in Babylon but not right away.
