The album is a concept album that details the fall of Lucifer from Heaven and the creation of Hell. The album is often cited as a classic of the doom/death genre and features haunting slow guitar riffs, beautiful soprano vocals, meandering keyboards/piano, violins, cellos and clear yet aggressive male growling vocals. All guitars on the album were performed by Johan Ericson.
"Death, Come Near Me" is a remake of a song off of the 2002 "Dark Oceans We Cry" demo. "The Apostasy Canticle" was originally titled "The Wings of God".
