Struggle for Azeroth:

Ashenvale

After the Sundering, the Night Elven civilization was built in and around the forests of Ashenvale. Some time later, Highborne foolishly attempted to convince the Kaldorei race of the power of magic by unleashing a magical storm upon Ashenvale, even though it was forbidden. Thus, the Highborne were exiled. Ever since, it has been in the caring hands of the Night Elves for thousands of years. It was not until more recent years that things changed, with the coming of the Horde as well as other much more insidious groups.
