"Nedgång" (Descent) is the fourth track off the Finnish folk metal band Finntroll's fifth full-length album, Ur jordens djup. A music video for the song was released in April, 2007, the month following the release of the album.
The lyrics of the song were written by the band's original vocalist, Jan "Katla" Jämsen—who was forced to retire in 2003 due to a tumor in his vocal cords—and make up the third portion of the album's narrative about the death and rebirth of the troll kingshaman, Rivfader (a character conceived by Jämsen in the early days of Finntroll after whom their first demo, "Rivfader", was named and who has been heavily mentioned in several of their later albums, including Midnattens widunder, Nattfödd, and Jaktens tid).
