This was the day everything changed.Taran Zhu yells: ENOUGH!! There will be no more bloodshed today.
Taran Zhu yells: I see now why your Alliance and Horde cannot stop fighting.
Taran Zhu yells: Every reprisal is itself an act of aggression, and every act of aggression triggers immediate reprisal.
Lady Jaina Proudmoore yells: They have undermined EVERY attempt at peace!
Lor'themar Theron yells: I must protect my sovereign people.
Taran Zhu yells: SILENCE! YOU must break the cycle.
Taran Zhu yells: It ends TODAY. Here. The cycle ends when you, Regent Lord, and you, Lady Proudmoore, turn from one another. And walk. Away.
The Horde & Alliance finally BROKE THE CYCLE, prevented further atrocities and mammoth loss of life, united against a greater monsterous threat that endangered the whole world, and allowed the writers to take the story to bold, new, creative, amazing, and incredibly imaginative directions.
So where were you on the day EVERYTHING CHANGED, when the Horde rediscovered their honor and identity, the Alliance agreed to forgive (but never forget), and both side finally broke the cycle?
