“Once upon a time, there was a gentle creature called the Dheerse, that lived in the forest. The villagers believed that getting kicked by the Dheerse would make them rich, so they chased him around until he ran away.” - A Yafutoman Fairy Tale
The Dheerse is located on a small island perched on top of one of the pillars in Yafutoma's outer wall. If you just keep following the wall, you'll eventually come across it. More specifically, it is on the western side of the wall, close to Mt. Kazai. If you hit Yafutoma, you've gone too far south.
