Hyjal is the site of Nordrassil, the first World Tree. It's brought back through the Caverns of Time so that players can relive the major event of Warcraft history, fighting with famous figures such as Jaina and Thrall.

The battle of Mount Hyjal takes place at the denouement of Warcraft III: Reign of Chaos, the seventh chapter of the Night Elf campaign, Twilight of the Gods. Archimonde advances the mountain just as he will in the raid instance, along with his lieutenants, Kaz'rogal the Doom Lord, Azgalor the Pit Lord, Rage Winterchill the Lich, and Anetheron the Dreadlord. Kaz'rogal is not present in the Warcraft III campaign mission.

Players can obtain Tier 6 glove and helm tokens from this instance. With many waves of trash, this instance is also convenient to farm at max level for The Scale of the Sands reputation.
