S01E01 Frontier Fort
Obsessed with discovering the fate of his father's lost legion, Marcus arrives in Britain to take command of a frontier fort. He makes friends with Cradoc, a British warrior, and all seems peaceful. Then, on...
After months of searching, Marcus and Esca meet Guern, the hunter. Now living as a British tribesman, Guern confesses that he was once a centurion with the Ninth, and tells them how the legion was annihilated. Later, at a tribal ceremony, Marcus sees the Eagle.
In Britannia in 130, a young Roman officer named Marcus Flavius Aquila and his freed slave Esca search for the Ninth Legion's gold eagle standard, which vanished with the legion 13 years earlier.
