Demon Raiders

"Okay. This is it."
Demon Raiders were pillaging bandits that terrorized rural Equestria for two years from 995 LB to 997 LB. They were called "Demon Raiders" because they wore armor that strongly resembled scales. Certain groups of Demon Raiders are responsible for the death of Applejack's and Big Macintosh's parents.

Their harassment of Equestria's suburbs was the last thing they did. Once their far apart and far-inbetween atrocities were discovered to be the works of the same group rather than a string of murders at the hooves of a single murderer, massive amounts of soldiers were deployed to end their reign.
