doesn't want the job of Emperor-heir

Emperor Augustus says fine, fuck you, I won't give you the job

happy for a few years

Augustus comes back, says "Everyone else died, I need you to take the job"

plead not to get the job

Augustus forces you to divorce your wife who you love and take the job anyway

become Emperor when Augustus dies

immediately plead for the Senate to take up its ancient prerogatives and rule

Senate refuses because they've all been replaced with lazy bootlicking bastards by Augustus before you came into power

spend a few years being a miserable and sad bastard but doing your job competently

finally get sick of it and retire to an island with near-zero communication with the outside world, because fuck everyone else

word gets to you that the guy you left in charge is just slaughtering people in preparation for a coup

go back to Rome reluctantly

execute a bunch of the stupid bastards who let it happen

die miserable, just as you lived
