I have a rough plot mapped out, but that won't materialize until CE is finished or a rerelease brings in more ROM hackers. The idea is to make an expansive 1020 A.D. overworld using 4 or 5 invidiual overworld "quadrants". Oceanic areas wouldn't be represented; instead, there would be sprawling countrysides, and each quadrant would be accessible by passing through a checkpoint related to political territory divisions. It'd take place during an escalating conflict, so that'd play a big role in opening up new areas for exploration in thievery.
But yeah, not enough human capital to pull that off yet.
