When the two Eon Pokemon, Latios and Latias, were found by an old couple when Alto Mare was just a small town, sorrow shrouded their still young and pure hearts, for they had lost a sibling in the chaos that brought them here. That sibling was named Latius, the emerald Eon. Old tales of Alto Mare read that when the father of the three Eons was captured by an ancient cult, was somehow stripped of his powers, and was reduced to an essence of himself. When the other three tried to interfere with the reduction of their father's powers, they were infused with some of his energy and image, turning them into the creatures named Latios, Latias, and Latius. Latios and Latias took their father's essence and infused it into an object called "The Soul Dew", but Latius went missing, and was never heard from since. Some variations of the legend state that he was chaotic, and evil, and thus was cast down and stripped of his powers. Others say that Latius was also captured by the ancient cult that captured his father, and they stole his powers too, thus reducing him to an essence, and sharing the same fate of his father.
But one this is for sure that is common in all of the legends of Latius: there will be a time when he will come again, specifically "When the Green shines in the midst of black". No one knows for sure why or when this event will become known, but when it does happen, the people of Alto Mare will be at last united with the Three Eons for eternity.
