Wars can divide families and neighbours. Good friends can become enemies in the face of war. Things can become edgy when a minion wants to send a letter to his friend on the other side. Perhaps he needs to make two carbon copies of his letter, one for his warlord and another one for the other warlord, lest the warlords become suspicious of what the minions do behind their back. You don’t want your warlord to think that you are conspiring a coup d’etat, do you.
