However many years ago, humanity discovered another plane of reality. This other word contained every single creature of legend and myth to ever be thought of existed. Dragons, kitsune, elves, spirits, gods, etc. Every single one. Humanity tried negotiating at first, but for one reason or another negotiation broke down. Humanity tried to wage war, but for so, so, so incredibly many reasons they were unequivocally defeated. Calling that battle a war would be an insult to all wars that came before it.

Humanity was then divided by a system called "Grab as many as you want and they're yours". 1728401-M was never alive for any of this however. He was born in a place called "The human farm for all needs". The HFFAN sells 2 types of humans. Ignorants and learneds. The ignorants were raised as humanity raised pigs and cows. The learneds were given 20 years of education. Both were sold off to whoever wanted to buy them.

1728401-M has just been sold to you.
