Paul Werner was a soldier back on Earth; a high-ranking officer, to be precise. He still maintains that occupation in Equestria, as a consequence of both the best and the worst events which brought him there in the first place. In the end, he knows for certain that he would never trade his current life now for the one he had. He felt it was tainted by the... circumstances surrounding it all.

He thought he was over it, and that he'd never have to face any elements of his past ever again. Paul was one-hundred percent right... in a sense. As he gradually found out, Equestria and the world it rests on has quite the lot of parallels to the Earth he left.

Especially one in particular, a mare who goes by the respective title and name of Generalfeldmarschall Aryanne S. Land
