The final song for the Tsai region in Season 4 of EC: OoNG!
This tune plays in a very, very large expanse of desert known to locals as the 'deadlands'. At one point, these lands were verdant and dotted with towns, before a river was redirected during wartime, thus robbing the region of nearly all of its water. The area dried up rather quickly, and the war eventually did, too. All that remains now are miles and miles of shifting sands, between bits of what were once cities.
The area is also prone to extremely nasty flash-flooding during sudden, unexpected rainstorms. It is the only surefire way between Tsai and Tykondrus (or Pentala for that matter) but as the sands are always shifting, navigation has to be done by landmarks, or by stars and the sun.
The area is also crawling with monsters.

These instruments are so kickass, and the melodies and percussion... sex for my ears LoL
