Getafex, the high priest of a Gaul village, wanted to find a successor for himself and teach his successor the magic potion, the key to the village's resistance to foreign invasion. Getafex led the village's most heroic warriors, Asterix and Obelix, to search all over Gaul for a suitable successor. Meanwhile, Sulfox, who was from the same school, disappeared for many years and colluded with the invaders, secretly starting a war for the magic potion.
