Warcraft Chronicle: In the explosion of the Well of Eternity over 10,000 years ago, Mount Hyjal in Kalimdor survived, and Illidan released the waters of the Well of Eternity into the lake at the mountain’s summit, turning it into a new Well of Eternity. Later, the red dragon planted an acorn from an oak tree in the new Well of Eternity, and it grew into Teldrassil_ the Crown of the World.
