Torvus Bog is the theme for the area of the same name found on Aether in Metroid Prime 2: Echoes. Notes of it can be heard in the theme of Dark Torvus Bog. It is playable in the multiplayer mode of the game after Samus Aran returns the Light of Aether to the Torvus Temple and reports this news to U-Mos. The theme is called Swamp World in the internal files, a reference to the area's internal name and name in concept art. It was composed by Kenji Yamamoto. The Torvus Catacombs theme plays on the lower floor of the Bog.
The theme can be heard here.
