Ages ago, on the island of Altomare, an elderly couple discovered two injured children washed up on the shore. They took the youngsters in, nursed them back to health, and the pair soon recovered. Not long after, however, monsters attacked the island, and it quickly fell to their fury. Then, before the old man and woman's eyes, the children they had cared for revealed their true forms as the Eon Pokemon Latios and Latias. Summoning their kin from the sky, the family arrived bearing a stone containing the power to drive the monsters away. That gem became known as the Soul Dew, and peace was restored to Altomare. In the present day, the criminal duo Zannâ and Rion seek out Latios and Latias to seize control of the Soul Dew. While taking a break in Altomare, Satoshi befriends Latias and gets pulled into the conflict, helping to prevent the island from being engulfed in destruction once more.
