Not a Chinese repeating crossbow? Oh, wait that was invented too early wasn’t it? Well, it was still in use during the medieval era at least. This is an interesting start that I would enjoy seeing both prequels and sequels to.

a wild game of capture the flag.. only with paper..
and the sword of the moon.. nice idea. you have motive, huge enemies, an insurmountable task, and symbolism. yes, epic tale already. :)
