Can the empire survive now that it down to just one emperor? Will it cope? Well, it should be fine as long as the man in charge in hard working - check; dedicated to the troops - check; looks to keep the empire protected - check; and doesn't massacre entire cities at the drop of a hat due to one person mentioning his brother... ah. Maybe Caracalla isn't the best man for the job... But he does have a fetching floor-length cloak with a hood that he can stand around looking evil in - that is that.
