I get what you mean. I maybe unfortunately happen to like the excessive, slightly ridiculous Iron Fist stories though, robot ninjas were really common in the early issues for some reason, and Nightingale Floors were a real security device in some ancient Japanese castles. 

That said I'll try and keep things a little less excessive if I go into origins of abilities or such from now on. I know we're trying to keep a certain kind of tone, sorry XD

Um, if you like I can easily say it was something he learned in K'un-L'un.
