Green Tracks or Blue Tracks (Japanese:碧い軌跡)[1] is a song used in Wild Arms 4 at the end of the Valley of Oblivion, where the heroes find the Holy Root they need to purify the water in Halim. It plays again when they return to town and Arnaud Vasquez and Raquel Applegate have a heart-to-heart about Raquel's fears of dying.
