The point? Well, there isn't one, really -- it's simply there to test the new interactive icons and make sure that players will be able to interact with everything. This isn't part of the storyline of Pandaria or anything like that. It's not an official quest that will be included in the final release. It's just a testing area.
However, it's one of those insanely weird, fun, unpredictable moments that you find when you simply roam around on the beta. If you're on the beta servers and you've finished everything there is to do, take some time to explore and see the sights. You never know -- you could find a hidden gem that won't be seen after the beta's over.
Oh, and in case you were wondering ...
It's open warfare between Alliance and Horde in Mists of Pandaria, World of Warcraft's next expansion. Jump into five new levels with new talents and class mechanics, try the new monk class, and create a pandaren character to ally with either Horde or Alliance. Look for expansion basics in our Mists FAQ, or dig into our spring press event coverage for more details!
