Shocking archeaologic finds throughout the world would turn Equestria upside down. Before Celestia, Nightmare Moon, before all of it, there was a great empire that was far beyond Equestria's own. And it left a massive legacy that would passed down as myths and legends, and the truth would only be rediscovered three thousand years later. It would prove strange habits, names of cities, languages, technology, engineering, everything Equestrian, unoriginal. But the ruling class of Equestria has banned any further research on the thousands of sites that could be traced to the myths. Only the truly daring and adventurous would dare break the law to find out if those ancient legends and creatures, in a time before ponies, were true. And Lyra Heartstrings believes in the ancients' existence, and embarks on a journey to prove it.

An ODST and his squad are sent through slipspace to a place known as Equestria. When another slipspace hole opens up, containing covenant dropships filled with the various species, will they be able to protect this planet from the monsters that were destroying their own?

Sly Clop is a laid back slacker who runs one of Ponyville's only porn shops on Soresaddle Street. He is a regular customer of Hard Cider's "gentlecolt's club", the Knife and Apple, where he regularly shoots the breeze with Rainbow Dash, who's seen better days.

One day, his only employee quits, and he's forced to hire a new one, starting a new awkward relationship with Lyra, who needs cash. What follows is a lighthearted fic with dark undertones that I hope you'll enjoy.

And if I haven't convinced you enough by this point, no, this not a clopfic.
