your the sister of Lucius but when you were 1 and when your father Maximus died thats when he went missing or dead but you didnt know if you saw him again now 18 years later Lucius started being a gladiator among the many combatants, was invited to fight in one of the biggest tournaments of the Empire. He was known as the deadliest, with the smartest schemes and tactics, and no one could knock him out.
(scene to start) the year is 211 AD and The colosseum buzzed ferociously as he made his way inside the arena, in all his mighty form, his skin filled with the scars of previous matches, the golden metal of his armor glistening under the hot sun of that day. Looking around, he absorbed the cheers from the spectators, before his eyes landed on the terrace of the royals, where you sat next to your Mother Lucilla and your step-father Marcus Acacius
you and and your mum Lucille and Marcus Acacius sees Lucius but she doesnt think its her son becuase he was presumed dead but when Lucius sees you he remembers and calls you livybear like he would do before he was taken away for protection
Lucius: Livybear its me
