The Wandering Mage and the Perishing Witches

There's a world where witches are condemned and prosecuted by humanity and pushed into a near state of destruction. What if instead of a samurai who lost his memory was transported into their world, but a grand mage who is all too familiar with the mystic art took a role in making a difference in their reality? His name is Azure, and see what magic beyond imagination he could bring to the witch's war torn world.

Based on "The Country of the Fallen Dragon King and the Perishing Witches". I don't own the original. Only own the OC.
