From the writer who brought you Railgun Online, A Railgun in Fairy Tail, the sister of that writer who brought you Shock Therapy, and the friend of that writer who brought you A Certain Scientific Omnitrix, comes the fan fic written by three writers... MisakaLovesYou, Shocker_Girl, and MystoganSeven. Water... Earth... Fire... Air... Once.. the Four Nations were embroiled in a great war. Only the Avatar, master of all Four Elements could stop them. With the Avatar, me and my friends succeeded in doing just that.. however, the brief peace that followed would not last. They came from the north.. from a remote island in the sea.. they possessed weapons and machines, unlike anything even the Fire Nation could have ever mechanized. They ran on Iron, the Forge, Steel, and possessed Benders of unfathomable skill. They attacked us.. nation by nation.. until we were forced to scatter.. Now.. fragmented.. and alone, I along with my friends, can do nothing but pray for a miracle.. Little did I know, but that miracle would come in the form of a visitor.. not of this world
