Seems I have a bit more to share. I found some old files that were attempting to document the last Birthright campaign I was running for some friends. It took place on a very small scale, in the Imperial City. The goal of the campaign was for the PC's to build their own crime organizations to take over the Empire (it was an "evil campaign"). There's very little there now, but you might like the introduction and brief synopsis of the state of the Imperial City's day-to-day functions. I'll try to add more from memory over time.
