As soon as he becomes an adult, he is banished to the frontier under the pretext of developing the territory.

On that land that has nothing but withered earth and rocks, Adonis is forced to live with his few companions, however he meets there a beautiful red-haired woman called Kalessa, who claims to bea "Dragon Witch".

Create a fertile land to start agriculture thanks to the blessings of the earth dragon and wood dragon...
