Operation Gnomeregan / Zalazane's Fall

During the latest maintenance blizzard has introduced the beginning of the pre-Cataclysm events with Operation Gnomeregan and Zalazane's Fall for the alliance and the horde respectively.

Rather then try to explain the events to you I will simply let you experience them yourself.  The first part of the quest is available to low level characters, but to finish the quest series you need to be level 75 or above.  These adventures give us an opportunity to finally take the fight to the enemy, and crush them.  So go, brave adventurers and take part in this epic quest.

User Criminy has made a thread about the event on the forums so after you lay down the hurt, drop by and share your experiences.  Feel free to share screenshots as well.
