As Guardian Med'an spared no effort in wielding the immense power granted by Algalon the Observer and unleashed the powerful skill Big Bang, he finally destroyed the World Tree Teldrassil completely. With the destruction of the World Tree Teldrassil, the fusion of Azeroth and the Emerald Dream also came to a halt.
