This plays in Salintus Desert, in Morheim. The other song that plays here is actually on YouTube, called Settler's Campsite.
I was looking for King Consierd for a while to take a picture of him, but the slippery bird just wouldn't show his face to me! ... Then I found out that a group of Elyos killed him, and then soon after, me. Haha.
Disclaimer:
I took all the pictures in the video.
The music belongs to Aion, NCsoft.
