Noel, along with the Hunter Organization, has been working with Equestria for quite some time now. With deals for protection and trade being implemented, the two sides have become stronger in the end for it with the new technology and magical techniques that have been borne of the alliance. To the outside observer, it would seem foolish to challenge the growing might of these two factions.
Tell that to the demons and other, greater, evils that have turned their sights to Equestria.

Part of the Wrath of the Harbinger-verse but non-canon. A ship-fic between Applejack's hat and Trixie's hat. I suppose stranger things have happened. Rated T for some language. Thanks to TP Night for the art, and Banana Prince for the idea from the "Write my fic for me" group.
