Sky SC Liberl News Issue 1:
"According to reports from the Foreign Affairs section, the Erebonian Empire, Calvard Republic, and Liberl Kingdom have all agreed to enter into a treaty of non-aggression. Preparations are already underway to host the signing of the pact following the Royal Parliament's approval of the terms
proposed by Queen Alicia."
Sky SC Liberl News Issue 4:
"Samples of the new model engines referred to in our previous article are to be presented to both the Empire and Republic
as tokens of the peace represented by this pact. These engines are said to be the key to next-generation flight and such technological exchange is the promise made to those who promise to uphold the harmony between nations. Much is expected from Liberl's ace in negotiations."
It was the Queens idea. And while I hate her and support Richard in every sense, I'll play devils advocate and explain why she did this. Erebonia has this fortress next to Crossbell where they built massive cannons aimed towards the city which sparked an international incident. This is a throwaway like in CS2, so it might be a Coldsteel invention, but apparently Calvard was not happy with the super weapon aimed at what they consider their turf and were looking to team up with Crossbell for an invasion. The Queen realizing this proposed this non-aggression pact just to save lives. This is why Erebonians in the Sky games are so supportive of the whole idea. Alicia is essentially a pacifist giving up her weapons so the 2 bullies don't kill each other.
