In the recent interview between MMORPG.com and Age of Conan's derector Craig Morrison, here are the essence of the interview.
There would be the largest content of quests and also the most impressive one. It has the largest population of NPCs, camps and encounters. You could in theory play through almost ten levels of game-play just in this area if you wanted to, so there is a lot of content there, and that's before you consider there is a new dungeon too.
The new area though takes it up another notch. There is a really cool story progression throughout the playfield that is inspired directly by own of the most popular of Howard's original Conan tales - The Frost-Giants Daughter. The player will be aware that something is going almost as soon as they enter the area and they can experience a great quest line that leads to Amphitheatre of Karutonia and ties into the fate of the Frost-Father himself.
Ymir's Pass has content for players between fifty five and sixty three. It's the largest and most diverse area, it has a broader scope of environments then any other location in our game world. From the forested, very typically Cimmerian entry to the playfield you will travel through volcanic regions with flowing lava, impressive mountain passes, all the way up to the frozen peaks high above. The story of the playfield triggers some really cool effects and sequences at various points that lead you into the experience in the Amphitheatre.
