Village on fire cos people ran in panic, knocked over a torch, and everything catches light
As for the knights bit I took that to be on purpose, Arthur's fathers idea of only nobility being knights meaning you would end up with wimps who wouldn't want to actually put themselves at risk, they all seemed sheepish about advancing, which made Lancelot look even better, maybe a little overdone but it worked.
Only real issue I've had is Merlin seemed all powerful doing making without using words, and since then even to move something he now seems to have to say something. All in all I really like the program though
