Ditherus Wart: (accidental) Gladiator

Ditherus is tempted into buying a sword from a mysterious peddler. Searched by centurion Marcus Furius when he gets home, Ditherus is thrown into prison when the sword is discovered and sentenced to death as a traitorous thief. Ditherus and his servant are taken to Gladiator School where the motto is 'Death or Glory - but most likely Death'.
