Tanbaga is an ancient monster of Skyriver, who has attacked the lands many years ago. Tanbaga is a demon of forest, who controls the plants growing in the ground of green earth. In his invisible form, Tanbaga can shallow people and creatures who get too close to a deep forest. These people are brought to a subspace of darkness.
