4,500 years prior to the First War, shockingly vicious and bloody battles erupted between the normally peaceful forest nymphs and taunka of Northrend. When word reached the night elfdruids of the Cenarion Circle, the elves conducted an expedition to find the cause of the brutal conflict. To their immense horror, they discovered that the roots of the World TreeAndrassil had reached so far into the ground that they had come into contact with the prison of the Old GodYogg-Saron. The malevolent being's energies had spread through the tree, slowly driving all lifeforms in the area to madness. As a result, the Cenarion Circle were forced to fell Andrassil, killing it in order to stop its suffering. Forever after, it would be known as "Vordrassil", or "Broken Crown".
