Rome, year 58. The shadow of the crucified extends over the empire while all Rome rustles with rumors. Nero, the new emperor would have poisoned his half-brother, Britannicus. Agrippine, to return in favor with his son would be ready to open his bed to him. Nero would have no thoughts except for Acté, the beautiful prostitute whom he ripped off from Pallas the freed. At the palace precisely, Nero charges Acté to announce to Murena that he is forgiven and that nothing opposes his return to Rome. Murena asks only that, but requires from his sovereign the head of Draxus, the killer of his mother. Draxus who committed this murder at the request of Agrippine... Nero then imagines a machiavelic plan that must lead to the death of Agrippine. He proposes to his mother to fight against a gladiast chosen by Murena. If Draxilus is the best-deputible entity, the character of the planet, which is the "respect of the planet's character, is the best-deputable of the planet.
