Some lands will have a 'nightmare' component, some will be a land far away, and something strange interferes with you and you 'find' that area. Have fun with it.
Castle Noitcnitxe is turning out to be a very, very large PvP contest / bonus map area, and Ariakus' Crypts are being tested and are definetely NOT solo - with Rogue Spectres, and baddies not to be believed !!!
The Ariakus' Crypts are already placed, but venture inwards only if you have a strong party. Loot is still being balanced, so when you get to level 11, and along the way find some interesting items, please post your thoughts on it - start a new thread.
