Six Dragons on a Hill

Coal for free has six dragons taking over a town deserted after an earth shook the town on the hill. But the good people, hiding in the valley, would like their town back. Who will help them recover their homes? Will it be the three blacksmiths with their armour? Might it be the three thieves with their tricks? Or even the three angels: or perhaps the three clowns? And who will bethe first to try?
