The Theory of Useless Magic

In the seventh year after magic disappeared from the world, society has fully entered the industrial age. Magicians, once powerful and respected, have been reduced to ordinary assembly-line workers. Evan, formerly one of the greatest archmages, refuses to accept this new reality. He makes a solemn vow to restore magic to the world and reverse the fate that has befallen all who once wielded it.
