Human's Industrialization Era (nov 1, 1492 – dec 20, 2009)

Description:

During 530 years, any forms of magic was completely lost and forgotten. The original gods became nothingness...nobody knew what they have done for humanity.
THIS is the apocalypse for magical creatures on Earth. Each new, they were seeing metallic monstrous machines destroying their territories and taking over their lands.
Gods were not answering to their prays anymore...they were all sentenced to die slowly but surely.
Gods sealed themselves in their world in order to peacefully work on other projects. They knew that most of their creations were going to disappear soon... They were about to lose hundreds of years of work and researches. But most of the gods didn't really cared that much...they were now able to create more developed creatures and living beings. The ones on Earth were only considered as prototypes.
But one goddess was against this mentality, Yumegami, the goddess of Dream. She was able to convince the "Millenial God" to seal and protect every species and forms of magic they created on Earth inside one of their old creation: the Metallic God. Even if this metallic monster is inactive and rejected by most of the gods cause of his "past", the "Millenial God" accepted and sealed all the species spirits and magical knowledges inside it.
After all...they might reuse it one day, who knows.
