The Legion’s emergence, however, had forever changed night elven society. The night elves had resolved to shun the practice of arcane magic because its reckless use had attracted the Legion to Azeroth. They cultivated a peaceful, naturalistic existence along the slopes of Mount Hyjal under the leadership of Tyrande Whisperwind. For many long years, Tyrande oversaw night elven governance, ever vigilant for signs of further demonic incursions. Much of this time was spent apart from her love, Malfurion Stormrage, who, alongside his fellow druids, upheld the balance of nature from within the Emerald Dream.
The night elves’ tranquil existence was shattered again when the Burning Legion launched a new invasion of Azeroth. At the height of this conflict—known as the Third War—the Legion and its terrifying undead Scourge assaulted the night elves’ lands. After awakening Malfurion and his druids from their slumber in the Dream, Tyrande gathered the other night elves, and they fought alongside the Horde and the Alliance to defeat the demon lord Archimonde and his minions at the summit of Mount Hyjal.
Although victorious, the night elves suffered greatly from the battle. Their beloved World Tree Nordrassil, created and blessed by the Dragon Aspects Alexstrasza, Ysera, and Nozdormu to grant the night elves immortality, had given off a massive blast of energy to slay Archimonde. To facilitate this colossal explosion, the night elves had chosen to forever sacrifice their protection from aging, disease, and frailty.
