In the end, Ragnaros, the Firelord and Azeroth's most powerful Elemental Lord, fell in regret. This time, unlike in the Molten Core, it was death in the truest sense.
Yet Ragnaros proved worthy of his status as the strongest Elemental Lord. Facing four opponents alone—the more powerful Guardian Med'an and three Elementals weaker than himself but still dangerous—he successfully inflicted grievous wounds upon Incendius and Neptulon the Tidehunter. Guardian Med'an and Thunderaan the Windseeker were also severely injured.
After defeating Ragnaros, Neptulon the Tidehunter and Thunderaan the Windseeker immediately took their leave. This was the Firelands, and remaining here by force would only continually weaken them. Only by returning to their own domains could they recover from their wounds.
Incendius once again absorbed Ragnaros's essence. His wounds rapidly healed, and his body grew even larger, but his aura still could not surpass Ragnaros at his peak.
A new Firelord had been born: Incendius. He was the most powerful Fire Elemental besides Ragnaros, and he also possessed the Mark of Embers, an artifact that commanded Fire Elementals.
As the new lord of the Firelands, Incendius naturally led the Fire Elementals away from the Old Gods' faction.
Thus, Azeroth's four great elements had all gained their freedom. Al'Akir the Windlord and Ragnaros, who had originally belonged to the Old Gods' faction, had both been eliminated, replaced by Thunderaan the Windseeker and Incendius respectively.
With Xal'atath's help, Neptulon the Tidehunter, who had originally been abducted by Ozumat, the Old Gods' giant octopus servant, also learned Ozumat's weakness. He successfully imprisoned him and prepared to tame him. Had the Tidehunter become an octopus hunter?
While Guardian Med'an was attacking the Firelands, Nefarian, the resurrected black dragon prince, and Onyxia, the black dragon princess, appeared here with dozens of black dragons.
