Speaking of excomms, we still haven't written up that NAP in this thread, as the rules technically require for enforcement by edit. So let's see.
Belated Treaty of Lasting-but-not-Eternal Friendship and Non-Aggression
The Most High Contracting Parties, comprising
the Basileus Romaion, the Shahanshah of Iran and non-Iran, the Most Puissant King of Bavaria, the Grand Duke of Finland, and the High King of Denmark, for the one part; and
the Czar of All the Russias, the Caliph of Dar al-Islam, the Most Holy Roman Emperor, the Sultan of Cordoba, the king of France, and the king of Croatia, for the other part;
desiring a period of peaceful preparation for the next conflict, and each believing that he will himself benefit more than his neighbour, have this day agreed the following terms of compact:
I. No sovereign of either party shall attack any sovereign of the other party, nor their vassals; and shall make swift peace on behalf of any vassal that attacks a sovereign or vassal of the other party, requiring no reparations or tribute.
II. No sovereign of either party shall send assassins to the realm of any sovereign of the other party.
III. No sovereign of either party shall accept a liege oath for any land now owned by a sovereign of the other party, whether by rebellion, diplomacy, or inheritance; but shall return any such lands without prejudice to their current owner. For this purpose it is understood that those boyars currently in rebellion against the Czar shall nonetheless be considered part of the Czar's realm.
IV. Poland is specifically excluded from all protection of this treaty, and is to be held an outlaw nation, beyond the pale of civilised law, to be dealt with as wolves are.
V. This treaty and compact shall last until the first of January, 1250; and past that time, all acts which have been held unlawful under this agreement will no longer be punished by God or man.
