Violence is the norm, not the exception.
Wars and rumors of wars. One cannot peruse the history of man without reading about endless conflicts, tribal massacres, and nations at war. Century after century, nations and empires arise and then cease to exist, often with war providing both the source of their creation and the cause of their demise. The aftereffects linger for decades: hundreds of thousands of orphaned children, widowed women left homeless, crippled bodies of survivors, devastated infrastructure, and enduring economic ruin.
