Two hundred years after Littlepip's death, her entire story has become nothing but mythology. As one group, the Church of Guardians, grew to preserve equality, and morality in the wastes, a stronger group of Raider Lords, Slavers, and other ponies profiting from the darkness grew to tear them down.
Another war broke out, and it didn't end well for the Church.
Fast forward another two hundred years, and the wastes have come back, only meaner then what Littlepip has endured. As a young buck wakes up from the brink of death, he finds he's lost himself. He can't remember who he was, what he did, anything. The only information he knows of himself comes in the form of small flashbacks as he dreams.
Now, he must learn to survive in the wastes, and discover who he really is.
