"Lock, do you know why Achineers are unable to create life? Why Agonias and Jacob, two of the greatest Archineers, ultimately failed? It is true that machine and man are similar. Organs, muscle... these can be copied with gears and cogs. Even intelligence can be programmed. Source can be manipulated to bring anything close to life. But life itself is defined by a soul. This cannot be created. It was meant to be this way - each soul should exist forever. I cannot fix Emi. Emi does not have a soul."
