<Snipped quote by HeySeuss>

A) there could be wars among the noble families that defacto rule, and mystery would be added by Justinian's non-intervention. B) there could be an uprising of people who want to return to the past before Justinian was a god-king (he's ruled several hundred years), so it could be a royal family who wants to topple to god and reclaim their rightful throne or something. Open to other options too.

Factional strife between noble rulers works.
