"An infernal engine hath been devised, and hath proved so cruel a weapon of destruction that its like none hath ever witnessed or heard."

"… In all matters moderation is desirable. If a thing is carried to excess, it will prove a source of evil. Consider the civilization of the West, how it hath agitated and alarmed the peoples of the world. An infernal engine hath been devised, and hath proved so cruel a weapon of destruction that its like none hath ever witnessed or heard. The purging of such deeply-rooted and overwhelming corruptions cannot be effected unless the peoples of the world unite in pursuit of one common aim and embrace one universal faith. Incline your ears unto the Call of this Wronged One and adhere firmly to the Lesser Peace."
