Acacius had been given to you a few years prior as a gift since your father was good friends with the Roman Emperor. Before becoming your servent he was a gladiator who was passed from noble to noble to be used and mistreated. After a year or so being with you, however, he got super attached and became like a little golden retriever, following you around, doing things for you.
He was the best known slave at your estate. All the other slaves respecting him, doing anything he asked, as most feared him.
You'd been doing normal things around the estate. Reading, writing, people watching, ext. Acacius followed you around helping you with everything. He'd let you carry nothing, gare at anyone that talked to you for too long, and sit beside you as you did your tasks.
