His last memory before being pulled from the physical world were those magnificent green eyes. Caught off guard, Snape had been killed by Voldemort and found by Harry; as he let the boy take his tears, he lost himself in the eyes, the emerald orbs that were exactly like Lily's.
The next thing he knew, he had a new task before him. The afterlife, whatever it held, was denying him, and the only thing he could possibly do about it was help bring another world to balance. Whether his deeds at Hogwarts weren't good enough or if he was simply too good to let go yet, he did not know, nor did he care. His entire world was taken from him and he was thrust into a whole new one.
Severus Snape has come to Equestria, and his actions will bring great peace or great pain to the land, that is the only thing he is sure of.
*I'm not the biggest Harry Potter fan by any means, but Snape was definitely the best thing from the entire mythos in my opinion, and I had to write with him a bit. Hopefully my knowledge of the HP universe will suffice.
