When Azeroth was young, the noble titans appointed the five great dragonflights to safeguard the budding world. Each of the flights` leaders was imbued with a portion of the titans` vast cosmic powers. Together, these majestic Dragon Aspects committed themselves to thwarting any force that threatened the safety of Azeroth. More than 10,000 years ago, a betrayal by the maddened black Dragon Aspect, Deathwing, shattered the strength and unity of the dragonflights. His most recent assault on Azeroth-the Cataclysm-has left the world in turmoil. At the Maelstrom, the center of Azeroth`s instability, former Horde warchief Thrall and other accomplished shaman struggle to keep the world from tearing apart in the wake of Deathwing`s attack. Yet a battle also rages within Thrall regarding his new life in the shamanic Earthen Ring, hampering his normally unparalleled abilities. Of even greater concern is a bleak and terrifying possible future glimpsed by the mysterious green Dragon Aspect, Ysera: the Hour of Twilight. Before this apocalyptic vision comes to pass, Thrall must purge his own doubts in order to discover his purpose in the world and aid Azeroth`s dragonflights as they face the Twilight of the Aspects.
