It's been 300 years, since humanity wiped itself out, leaving behind a single witness - forever cursed, to wander the ruined earth.

A former soldier - now alone and hurt, he struggles to end his suffering, only to be transported to Equestria in the process. Little does he know, the role he will be forced to play - in shaping the fate of this strange new world...

Notes:
1. Marked 'mature' because of some gore and strong language (used from time to time by the OC).

2. Some gore is there - but it is used mostly to visualize body damage from battles and accidents, few torture scenes are there too, but they are short - not exactly the 'cupcakes' type.

3. I advise you, to read at least the first four chapters, before giving up.
