Long ago, there was a country named Doutenpuku, where sennin called Dousen
existed. Using Feng Shui arts they could make underground Enchanted Caves and
with them reactivate Earth's source of life, the Dragon Vein, so the land
could regain its former greenery. That was their mission.

However, people in the land were puzzled by the Dousen's behavior. With all
those bizarre monsters being summoned underground and such, they thought it
was something evil. Bounties were placed on the Dousen's heads to drive them.
As gossips spread, many people even from other countries, such as adventurers
and men testing their skills, came to challenge the Enchanted Caves.

You are a Dousen apprentice.
