What happens when a group of terrified people end up not in Equestria, but underneath her lands, in the tunnels of Diamond Dog City/States. What will happen to several hundred people ripped from their own world and thrust into a new world where they have nothing, not even the clothes on their backs?

Demanded by my wonderful readers as the first side story that I write after finishing the second installment of The Unity Pact series. Idea credit goes to Iron Sky for the concept and impetus. There are some parts which are dark and sad but those are not the main theme here. Reading The Unity Pact and The Unity Pact 2: Shaking Foundations are not strictly mandatory, but highly recommended or else everything will seem out of context.
