Well, when I said Build, I should have said Build-except-Build/Construction. I think it's the same stuff that magma destroys.
I was very much amazed the first time a dragon came through and carefully destroyed every one of my stone floor grates which were supposed to keep out the riff-raff from my light channels over my indoor gardens. It was then that I learned to make glass blocks.
Then I learned that stone blocks transmit light every bit as well as glass, in DF.
Isn't the fire breath of the dragon amazing? I was astonished at how good it looked, in an ASCII game.
