Rage- that unreasoning swell of feeling that stops all thought in its tracks. An uncontrolled maelstrom that builds and builds, hidden until it erupts like a fountaining geyser. It is uncontrolable, unreasoning, uncaring, terrifying, and it leaves devastation in its wake. It is a thing civilised creatures fear beyond all else- for rage makes the meek unpredictable, dangerous, and the fierce lose any semblance of humanity.
Time speeds, mind snaps; primal instincts take charge. Muscles tense, eyes narrow, teeth bare in a horrible parody of a grin. Then, as it drains away like water off a beach, his eyes slowly clear and he sees the destruction around him, (pained eyes in front of him), and he is struck with the horror of what he has done.
