The portable forge machine was a marvel of technology, Alex's was luckily a spirit grade forge, which meant to some extent it has a consciousness of its own. It was a common consensus that equipment and tech in the spirit grade developed spirits of their own, or rather souls, and the higher the level of equipment, the more conscious it would be. By virtue of such an existence, it becomes that much more easier to design weapons with the forge, especially since this particular forge already has a design program uploaded into it.
