The Egyptian Queen Cleopatra bets against the Roman Emperor, Julius Caesar, that her people are still great, even if the times of the Pharaohs has long passed. She vows to build a new palace for Caesar within three months. Since all her architects are either busy otherwise or too conservative in style, this honor falls to Edifis. Edifis calls upon an old friend to help him out: The fabulous Druid Getafix from Gaul, who brews a fantastic potion that gives supernatural strength.
