Pokémon Melos: Destruction's Symphony

All Delta had ever wanted was to be a trainer, possibly even the best there ever was, but a chance encounter with a young thief sends the two of them on a crash course with destiny. Hounded by a mysterious group, the two must navigate the Sinnoh region while uncovering a dark plot to change the world as they know it. Mostly OC cast and set 15 years after the DPP games.
