Fallout Equestria: Hightide is a sidestory written by King of Malta.
Precious is the Pretty, Pony Princess of Stable 81 and if anypony says differently... a heavy object usually finds their faces. That was at least, until a break out attempt by the Tunnel Stallions leads to her finding herself in the ruins of Baltimare. Without servants, her dresses, or even a shower she must learn to live without her lofty lifestyle and make friends...both which seem very unlikely. For Baltimare is a city crumbling into the sea, and the darkness that lies within threatens to rise.
