I find mine usually goes cold 
I thought yours normally ended up with paint brushes in it.
Anyway, liking the look of the Lindorm Eng! Can't wait to see the beasty with some paint slapped on it.
About those dwarves. Im not sure about the metal parts on those. Should I go with silvery "mithril" or more redish copper or bronze. I have also thought about the blueish tones on the metals as my heroes?
Maybe a mix would be the best answer.
It would make sense that the Dwarves would have their own secret metal recipe, resulting in a different coloured material. Still, whatever you decide I'm certain it'll look damn cool.
