Jacob doesn't consider himself a special individual. Average, maybe. Intellectual? far from such. He has show interest in history in the past, though. So when he winds up in Equestria through an ancient ruin that still contained a fifty thousand year old magical charge, he becomes very interested in history. He decides to look more into Equestria's past, the time before the ponies arrived there.
Luckily, he won't be doing it alone. The Princess of the Night has shown a recent interest in history as well, and together the two explore ancient relics from Equestria's past.
When they find something during the exploration of an ancient buried chamber though, everything changes for both of them.
Warning: It contains vore.
