In ages long forgotten, when Earth found itself on a collision course with a meteor, Legendary Pokémon Arceus used its power to avert the danger. However, this feat caused the 16 Plates surrounding it to scatter across the world. Without the Plates providing Arceus with life energy, it began to die. A human named Damon managed to find one of the Plates and returned it to the moribund Pokémon, helping it recover. As a reward, Arceus created the Jewel of Life and gave it to the people of Michina Town, stipulating that it must be returned, but the humans refused, hogging the Jewel to themselves. In the battle that ensued, Damon was killed and Arceus went into slumber, vowing to punish humanity upon its return.

The situation takes an unexpected turn when Arceus, despite Sheena's best intentions, remains unsatisfied.
