Barrow Deeps

The Barrow Deeps is an ancient cave system beneath Mount Hyjal. Barrow dens, where night elf druids go to sleep, lie scattered across the land, and it is said their winding tunnels all lead to this one place. No one knows how far or how deep the tunnels run. Three entrances lead in, and one of them lies on Mount Hyjal. To the night elves the Barrow Deeps is sacred.

For thousands of years the Druids of the Claw slept here, and the Watchers, led by Maiev Shadowsong, kept prison vaults in the caves. After the War of the Ancients, Illidan Stormrage made a second Well of Eternity, and for this he was locked away in the Barrow Deeps for ten thousand years. In the Third War, Malfurion Stormrage and Tyrande Whisperwind came into the caves and found giant spiders twisted by demonic corruption. Tyrande freed Illidan from his prison. Malfurion found the Druids of the Claw, who had slept so long in bear form that they believed they were bears, and woke them with the Horn of Cenarius.

The night elves still hold some of their most dangerous prisoners here, and rumor says an infamous demon hunter was once kept in its cells. They are slow to let anyone in, even their allies. Like the furbolgs of Blackmaw Hold, they may now be dealing with some kind of corruption.
