The Dolmen is a new zone coming to Age of Conan in future patches. There is no release date for this zone. It is designed for level 50 to 55 characters. This zone should add "dozens of hours of content"
The Dolmen is a mountainous zone, infested with Bandit forces. The "wheel of pain" structure that is seen in the 1982 Conan movie is in the mountains.
Gamespot had a chance to do a sample quest while at the Game Convention. The quest will have you light signal fires around the region in order to call reinforcements to help a settlement under attack.
