I have become accustomed to the noise in the background in Ancient Nord Ruins, so much so that I often pause the game and leave the sound on while I perform other tasks about the house. It is a very strange noise kind of like wind in a way but at the same time not! Yesterday my friend called and I had just left that noise on in the background. After we had been chatting for a couple of hours she turned to me and said what the .... is that noise! Ooops I hadn't even noticed it was still on having gotten so used to it...
