Pretty much a prequel story to "Anonymous impregnated the main 6, AT THE SAME TIME". It tells series of bizarre heroics that leads to Anonymous (ahem) putting the buns in the ovens of the main 6.

This is not a clopfic or anything. Anonymous the greatest hero of Equestria of all time became romantically involved with the human Main 6 at the same time. Now he gets to pay the 'price'.

A man from a distant space age future arrives on Equestria. He makes first contact with its residents and explores this strange universe, while finding a way back home and dealing with the death of his friends.
