The Hub City Avalon was different from Hub City Evalion. Evalion was the home of Evotech's Headquarters, which also made it the technological capital of the world. As for Avalon, it had an equally domineering title. It was the world's industrial capital.
Anyone with talent in creation or construction-related fields, as well as researchers who preferred more mechanical experiments, would flock to Avalon, creating an environment of constant productivity and growth that allowed the city to pump out products at a frightening pace.
Of course, not everything in Avalon was moving fast. There were some projects far too large or complicated to match the flow of the rest of the city. But even a single percentage of growth in these projects was related to tens of hundreds of completed smaller products. Their values couldn't be prepared.
