The Crystal Wastes. One of the most dangerous, mysterious countries known to ponies. So dangerous, in fact, that the Crystal Empire itself refused to acknowledge it as a sister nation. When Sombra's armies descend on the Empire, a handful of soldiers, engineers and scholars escape the devastation. Forced into the Wastes to escape the threat, they discover that a long-dead civilisation isn't so dead after all.
