The War of the Spirits

The forests of the Kasumigaseki Mountains are deep and dark, evoking the aesthetics of myth and legend. It is believed that here in the mountains, at a location known as the Hill of Spirits (レイヶ丘), that a Shinto priest named Otsuka Yoriyuki was contacted by the spirits. The legend says that while Yoriyuki was traveling through the mountains he came across a hill covered in flowers of every imaginable color and shape. While appreciating the flowers' beauty, Yoriyuki was approached by a kitsune who claimed to be a messenger of the Goddess Inari.
The kitsune told Yoriyuki that many kami and yokai had come with the colonists to their new home, eager to bless and aid the colonists in their times of need. However, the kami and yokai from Sol were at war with the native kami and yokai, who were insulted by the colonists lack of respect. Even worse, because of the colonists' lack of veneration towards the kami and yokai that had come with them meant that they were losing the fight against their native counterparts. The kitsune begged Yoriyuki to inform the King that unless proper veneration was given to the spirits the colony was doomed to disaster. In addition, the colonists were instructed to learn the names and needs of the local kami and yokai, so that they to could venerated appropriately. 
When the king heard Yoriyuki's message, he ordered the construction of shrines in every settlement on the planet.  Funds were set aside so that each homesteader build shrines areas where they believed the spirits were the strongest and rewards were handed out for discovering the names, personalities, and needs of the local kami and yokai.  The battles between the old and native spirits were recorded, and their sites marked with monuments.  As the colonists venerated the spirits they began to have richer harvests, locals predators left their herds alone, and cures were found to diseases that had previously ravaged the colonists.  In this way the colonists learned to respect the spirits and Eiennohanan Shinto was born.
