I wanted to reflect the sadness when the Klyros left their world and the pride they achieved when they "defeated" their opressor. The drip sounds symbolize the the wet atmosphere. A careful tone is present that symbolizes the waryness of the swamp.
I wouldn't want to change this tune, other then enhance it's message. To me, this is Klyro's history. The Klyro's have always met oppressors but they push on. I wanted this song to be a reminder of the past, never forget the pain that once was Klyros, a tombstone for the fallen and lost ones.
