The Story of the Orphans of Civilization Before Arknights

A book born out of a bet between three people If there are three more orphans from the former civilization that have never been seen before, how will the story of Terra change? Will it bring a new hope to Terra? Or will it bring destruction to Terra? I don't know why, but the work tags are all irrelevant to the content. I can't change them yet. I'm convinced.
