The fog was originally going to be added but the original piece wasn't tiled properly. The dragon is getting an updated version later tonight but for now it is just gliding with one sprite for now, but more are being made by the artist.
To run this mugen stage go to your Mugen.cfg and make sure to have it set as followed:
