From yesterday's patch:

New Adventure Zone moves to Live
-----------------------
- The adventure zone currently on Stormhammer will move to live servers. You can visit the Lost Pyramid of Galuuk Korr. This midlevel adventure zone will allow you to explore a monument from the lost elvish city of Takish Hiz! Now you must find what was left beneath the sands. Good luck.

Can anyone enlighten me where this is? I tried asking in ooc, friends and no on knew.

probably something of an LDoN zone, just have to get lucky when you choose the adventure

I beleive its a new NRO zone, But for for Lvl 50 and under. If I am wrong please Correct me.
