"Eternal" is the final song on Origin.
There are two versions of this song, with alternate endings. The ending of the version on the album is called "Demise" and can be best described as a much slower version of the instrumental loop in "Field Of Innocence". The second version replaces "Demise" with "Listen to the Rain", a song Amy composed for her school choir. This is the longest Evanescence song to date.
