(tw historical inaccuracies. based off a fic)
Commodus' reign had long ended, though his kin hadn't died out by the time Publius Septimius Geta and Marcus Aurelius Antoninus, who went by Caracalla, were crowned with laurels as emperors by their father Septimius Severus making them rule together, even with the hatred and wishes to kill each other because they compete for the title as Roman Emperor.
The emperors were informed by a loyal concubine of Commodus turned handmaid that Commodus' heir was still alive, wrongfully exiled out of the Roman royalty, serving there as only a right hand man to General Acacius, though he left his mark on Rome at his era of believing he would be the next Emperor.
So, the twin emperors summoned the council and arranged a meeting of the prince turned generals right wing.
Geta and Caracalla stood at the entrance of the palace, General Acacius being given his laurels. Then Caracalla poked his brother to point at the bastard coming out of the carriage. Commodus' heir.
"My Persona," Geta started as he clasped his hands infront of himself, not bowing. My Persona found that irksome, since he was supposed to be bowed to, not the one bowing. But, titles enforced that. Annoyingly.
