Lund Empire, Creating with Forges

The Lund Empire is a colony of forgers who build houses that are immune to catching on fire or melting. They do this because they use the entire city as a forge, making it hot enough to give things life. For example, the city around the metal/obisc dragon is currently in forge "form". The people of the Lund empire are creating a huge dragon they will give life, and are using the immense heat of the city to give it life. It might interest you to know that the main point of the story is finding the center of the earth, to make a creation so huge and powerful that there is full dominance. Like the concept?
