Storyline

There were three Pokémon that protected the Johto region. They were called the Legendary Dogs, and they often wandered around the region. One day, they decided to hide in the Brass Tower in Iris City. At that time, it was a city full of tourists from many regions where legends from all over were shared. The Brass Tower was built in honor of Lugia, a foreign Legendary Pokémon. It is said to be the Pokémon of memories, and people who entered the tower would often recall forgotten memories. The Bell Tower was built in honor of Ho-oh. It was rumored that when it shows its rainbow-shaped wings, the person who looks at it becomes immortal. Once, the two Pokémon happened to be in their towers at the same time. They faced each other, and their fight caused a fierce storm. Lightning struck the Brass Tower and it caught fire with the Legendary Dogs inside. They sadly lost their lives and their souls rest in the Burned Tower. One of the three Pokémon dropped a crystal shard that made certain Pokémon change shape, but only a good trainer could handle it. Maybe that trainer can free those souls. Meanwhile, foreign Pokémon are immigrating to Johto. They're hiding from other Pokémon, as they haven't yet adapted to the region. Professor Oak gives you a Pokédex to research them.
