Rage of the Firelands
In the days immediately following the Cataclysm, the Firelord Ragnaros and his minions attempted to ravage the world even further, pushing a damaged Kalimdor over the brink of oblivion. Their invasion was turned away at Mount Hyjal, but the threat of their presence lingers. It is not enough to simply deflect the danger posed to Hyjal, Nordrassil and all of Azeroth – it must be ended.
In patch 4.2, it’s up to you to push the conflict back from the peaks of Mount Hyjal into the endless blaze of the Firelands – to lead a full-scale invasion of the elemental plane of Fire, and do battle with Ragnaros and his minions in their very lair.
Prepare yourself for war.
The time to strike at Ragnaros draws near. The battle to protect Mount Hyjal now rages in the depths of Ragnaros's smoldering realm. As territory is gained by Azeroth's defenders and they draw closer to the inner sanctums of the Firelands, a monumental task awaits. Ragnaros's lair--Sulfuron Keep--is closely guarded by his most loyal servants, including the traitorous Druids of the Flame and their mysterious leader. Yet the brave heroes who have ventured into this ash-choked domain cannot afford to shy away from any danger. The outcome of the battles that lie ahead will determine the very survival of Azeroth.
Dragonwrath, Tarecgosa's Rest
Uncertainty looms over the blue dragonflight's domain, the Nexus, as its members struggle to appoint a new leader. Split between the two likeliest successors--Kalecgos and Arygos--the flight has agreed to meet during a rare celestial event known as the Embrace in the hopes that a new Aspect will finally be chosen. The bronze dragon Anachronos, however, has detected something sinister at work around the Nexus, threatening to compromise the ceremony. If a hero does not rise to investigate these dark forces and uncover their intentions, Anachronos believes that Azeroth's doom is imminent.
The Regrowth and Molten Front
Although the night elves and their allies repelled Ragnaros's initial invasion of Hyjal, their work on the sacred mount is far from over. Archdruid Malfurion Stormrage has gathered his comrades at the Sanctuary of Malorne within the newly healed Regrowth to invade Ragnaros's domain: the Firelands. Once inside the Elemental Plane, Hyjal's defenders hope to establish a permanent stronghold. Yet these plans have come under threat by a ferocious new elemental assault that has swept through the Regrowth. Despite this setback, Hyjal's protectors remain steadfast in their mission, for they know that it is in the molten heart of the Firelands that the fate of Mount Hyjal will be decided.
What was to be an auspicious event at the ancient World Tree Nordrassil has ended in tragedy. There, members of the Cenarion Circle and Earthen Ring, including former warchief Thrall, had gathered with the noble Dragon Aspects to unite their powers and restore Nordrassil for the good of Azeroth. Yet word has now spread that a shadowy Twilight's Hammer agent interrupted the ceremony and struck down Thrall with dark magics... casting his spirit into the four domains of the Elemental Plane. If these terrible rumors hold true, the Earthen Ring--indeed, all of Azeroth--has lost one of its greatest champions.
