Side story to Horn And Wings

Luna has been having troubled sleep and blaming herself for the death of Sharp Biscuit, her bodyguard and close friend. The recent invasion from the mirror world troubles her and she wants to make sure nothing ot that sort happens again. That, unfortunately, might involve some rather drastic measures.

Equestria seems to be safe though. With the new peace treaty between queen Chrysalis' hive and Canterlot even the paths through Everfree Forest are safer than they have ever been and the official addition of the fourth princess helped with foreign policy a lot. Still , Celestia is worried about a second hive that came along with the last invasion and their enmity towards Luna that might prove dangerous and she sends Twilight Sparkle to negotiate the terms of peace that would be respected even by Guiding Light and her hive.
