Ooh, Byzantium, yes please. And whilst Theodora would be very welcome, I've always had a soft spot for Irene, even if she did have her son tortured to death. You could have great fun with the Iconoclasts being all about getting rid of some sort of MacGuffin, and you've got Charlemagne and Haroun Al-Raschid running around at the same time. And all the companions expecting, well, the Dark Ages and finding Constantinople is bigger than Sheffield and has sewers and baths and sports hooligans... but also streetfighting monks, legalised and systematised mutilation, slavery by any other name etc. etc.

YES a chariot race, certainly. I can totally see Yaz as a charioteer. Of the Blue faction, obviously!
