Sidonius is a former gladiatii of the Remus Collegium. Earlier in his life he had served Darius Corvere as a Luminatii for five years. He wasn't present when his Justicus and Gaius Antonius were captured but instead got beaten near to death, branded as a coward and sold off into slavery after he didn't want to march on the capital. After six years in chains he ultimately gained a spot in Leona Remus's collegium.
