Seekers

The world is old, five billion years old to be exact, and in that time so many things have happened that are now forgotten. Heroes who have lived a life of adventure become myth and the adventures they had become nothing more than stories. As the next generation overlapped the old, the history of the world became warped and false. But there is one thing in this world which has withstood the test of time while history did not. This was the artifacts that were left by the heroes and villains who wielded them before they passed away, and these artifacts still remain in this world to this day. But these artifacts pose a threat to the peace and harmony of Equestria. Therefore, under the authority of Princess Luna, a team of specialists was created to search, collect, and document these dangerous artifacts before they fell into the wrong hands. These group of specialists are known as the "Seekers", and it is this group of specialists which keeps Equestria safe as they work in the shadows. The less Equestria is aware of the dangerous weapons that exist in this world the better as they say.

After all, it was Princess Luna who said this.
