What really happened (Elves attack on Orcdar!)

The Elven Alliance attacked Orcdar and hundreds of elves died, so as hundreds of them survived. Allerie Dorhiel was thought to be dead as well but she wasn't. Allerie disappeared during the battle, she was taken by Nagash, however, Allerie managed to get free but she got a curse. She got blue eyes and her skin changed color to blue. She revived a few hundred elves and made an army. The army lived in peace in an old castle near The Bronze Mine.
