This follows right after Quilava's first Equestrian encounter. Mystery dungeons have opened in Equestria, so pokemon are spreading all over Equestria. Unknowing the dangers Twilight, Luna, Rainbow Dash, and Quilava enter the mystery dungeons
I'm a big fan of Pokemon and MLP so most stories will be crossovers of the two. I am also a big fan of Valve, so I might make a crossover or two with the valve universe.
