This is a simple and short rework of Wingfried von Katerinburg's backstory from Equestria at War Mod.
I always felt that Wingfried's backstory was lacking at best, especially so considering the fact that the mod itself doesn't even give us a reason why he started hating ponies, which is the entire point of his character.
Now I am not blaming the people who wrote the original backstory, considering that the writer in charge of it probably had to do a dozen other Bios and couldn't spare that much attention to a certain character's background.
So, instead of making him a cheap two-dimensional villian that was designed specifically to be an annoying loser who was needlessly evil for no reason at all, I instead decided to give him an actual tragic backstory that would give him a reason why he is doing what he is going right now.
Hope you enjoy it.
