"Well, you see, Veraxitoc, normally, either Wallace or I would clamp down on Finnegan. However, that only leaves one of us to speak." He said, "So, what Im having Shamgar build is a dragon-proof, dragon-sized muzzle."
In the other room, Shamgar was busy as a bee. He pulled out his tools, which included a hammer, tweezers, a wrench, and a special tool he made for cutting metal. How it worked was that he channeled weak wind spell through the shaft, and focused it all at the end of the tool, producing a blade sharper than a razor blade.
After finding some scrap metal laying around, gathered from old armor, he started making the frame for this muzzle, hammering and cutting the steel into shape. Fitting the straps on his invention, he brought it out, and presented it to the others.
