Apologies for the delays! I've not forgotten about the project (promise!), and I've got some half-finished builds in my pile o' shame! At the moment I'm having a bit of a think about how best to focus things (based partly on availability of sources), and trying to get hold of some actual Byzantinists to make sure I'm not making any glaring errors, and to make sure I don't play into any harmful myths
(Plus sculpting is a slippery slope and I get very tempted to work on some Italians or Ottomans!)
