Game concept
White Peace
From the game's encyclopedia
A White Peace is one of three possible Peace Offers. Sometimes, both sides will agree that the War is no longer worth pursuing.
With a White Peace, the Attacker typically still loses some Piety or Prestige, but far less than with a humiliating Defeat.
