Yes, i was confused by the busyness of the frames aswell.My guess would have to be for either the water or lightning,could be wrong but thats what i guess.I would say water because the piping would have to be something they'd be very good at building and bringing to the city in terms of advancement.And lightning possibly because they could have figured out a way to hav more civilized technology through proper advanced piping.Althogh knowing the leader,it's probably one we've never seen that few know about.


Out of curiousity which chapter was that again?
