In the bowels of Canterlot's mountain is a long held secret that has been going on for years upon years. After Luna's demise, a group of ponies started the Nocturnal Gauntlet, where ponies fight for the enjoyment of others and for the rich to invest into. For hundreds of years this has gone on under Celestia's nose in secrecy. Spare Change, however, doesn't believe that it should for much longer.

(If anyone knows of a better suited picture, please let me know of it! :P)
