Using the hearth of sin he enhanced his army’s and nearly succeeded in his battle against Lucia. But she used the power of her crystal to destroy the lands, which is the origin of the floating islands.
To prevent being defeated he used his magic to save his essence, and hide the crystal until it’s powers could be restored. And so has passed 1000 years Larhamal has now been awakened thanks to Ophilia.
