Then a great sound boomed over the plains; a single ringing peal that rose majestically into the air, reverberated across the empty land that once had been the site of a thriving, prosperous nation. The first part of the legend had been fulfilled. Then, suddenly, chaos reigned. With a great thundering that shook the ground upon which they stood, the gray tower exploded in crimson glory; a great mushrooming blossom of red fire erupted skyward hurling the assembled Tarthans to the ground where they lay in numbed stupor.
