Loose Cargo (Side Quest)
This one triggers when you hear cries for help at the Zoiontegoi Shipwreck, in Herakleion Nome.
Clear away the wild animals, then free the Roman from his cage.
Speak with him after to learn about his career, and his future. The end of the conversation ends the mission.
You can score a little extra XP by sniping any animals than menace him as he leaves the area.
