Three years ago came the Winter War.
The Weasels, long our enemies, became our bane, as they smashed through our Southwesterly borders.
By the wit, wisdom, and leadership of Gwendolyn, Matriarch of the Mouse Guard; and no small measure of Guardmouse sacrifice & blood, we beat back the Weasel horde, but at great cost.
Our Southwestern border is not what once it was. Several mouse communities were lost, their citizens now homeless, or worse.
The Weasels threaten our borders no more, but in their absence a new danger threatened.
Disgruntled by the 'performance' of the Mouse Guard, various 'free Mice' answered the call of Midnight, to usher in a new era of Mouse dominance, both over other animals, and over other mice.
By the actions of the Guard, Midnight's army was broken at the gates of Lockhaven, the Mouse Guard's home & Sanctuary, but Midnight's poison had spread far & wide among those mice who had grown fat & powerful in their homes, and who saw little need to recognize the efforts of the Guard when it meant letting go their own dreams of empire.
The Winter War is done.
Midnight is banished,
but the Mouse Guard, and by extension all the Mouse Territories, are the least stable they have ever been in several lifetimes.
Are you the mouse to step forward & do what needs to be done?
