Well, I know the emperor is really well liked at the time but ultimately a failure. He's also kind of an arrogant dick, so I'm not stoked about being his 'loyal general.' Especially considering the one we also have an option serving ends up being humiliated and exiled in a fit of paranoia, despite being successful and loyal. Irene dies without note, I'm pretty sure the Varangian guy is the next emperor, and the patriarch does his best to keep his head down while the emps is going full sun king.
It also bears noting that the current emperor is the one that drove our father into destitution and death, presumably over being insecure of his talent and success.
