There is not much detail in the legends of Janno. The region was thought to be a desolate area over 500 years ago. Crops couldn't grow, and people and Pokémon hunted each other for food. Then the Legendary Pokémon galloped over the region, creating plentiful fields and an ocean that covered over half of the region. After their help, they taught people and Pokémon to be friends. After the two Pokémon ran off, the people and Pokémon of what was now called "Janno" worked together to build towns for people to live in. The citizens of these towns decided not to build them too big so they would not destroy too much Pokémon habitat. Though in the future that was to come, these old towns were modernized and their size was extended.
