World of Warcraft: The Story So Far, Part One

In preparation for the December 7th release of Cataclysm, Blizzard Entertainment has begun a series of new "The Story So Far" articles over at the expansion pack's official website. Part one briefly covers the storyline up to the shattering of Azeroth:
Believing that the new warchief would lead the Horde to ruin, Cairne challenged Garrosh to a duel of honor. Although the mighty tauren fought valiantly, no amount of strength could have led him to victory. The matriarch of the Grimtotem tauren tribe, Magatha, had poisoned Garrosh's blade, unbeknownst to either of the duel's combatants. Cairne became immobilized after he received a flesh wound during the battle, allowing the new warchief to land a killing blow.

Following the duel, Magatha's agents seized the tauren capital of Thunder Bluff for the Grimtotem. The usurpers also intended to murder Cairne's son, Baine, but the young tauren eluded his assassins and staged a counterattack. Ultimately, Baine and his forces reclaimed Thunder Bluff, expelling Magatha and her traitorous followers from tauren lands forever.

Unaware of these critical events, Thrall received an ominous warning in Nagrand from the Fury of Earth: the fear and turmoil of Azeroth's elementals echoed the condition of Outland just before that world then known as Draenor had been ripped apart. Yet Thrall had little time to act on this unsettling revelation....

In a sudden upheaval eclipsing the world's recent elemental unrest, Azeroth shattered. Violent quakes tore through the earth. Mountains of fire and magma burst from the ground. Colossal tidal waves obliterated coastlines and caused widespread flooding.

The Cataclysm had begun.
