This story is a sequel to Imbalanced

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.

This story is a sequel to Diplomatic Relations

There are two sides to every coin. It is true that Icy Gaze was imprisoned for capturing all Element bearers and almost killing them, chickening out at the last moment. It is also true that he did all that for a sum of money a pegasus of his career almost never has the chance to see and on the orders of princess Luna, possessed by Nightmare at the time.
It is understandable why he might be just a little unhappy about his current home, Canterlot castle dungeon cell, and wants to spread his wings again.

Also, Twilight "I'm not insane, stop asking!" Sparkle attempted to build an artificial intelligence to serve her needs and finally activates it.

I'm sure a pegasus and a bucket of bolts won't end up going against each other.
