What will happen if the Four Knights of Gwyn have to fight against the Grimm? No storyline, just the actions. Five oneshot, four knights (M to be safe, as there is lots of gore in here)

The Rock Hard Gladiators are coming to a new world... Are they ready to face the Grimms, as well as the evils there? (pairing undecided) (summary sucks, really)(I'll update slowly, since the notebook which contains the main storyline for this one is lost)
