The lyrics to "In Their Darkened Shrines IV: Ruins" are borrowed from the H. P. Lovecraft short story, "The Nameless City". These lyrics are not actually spoken in the song, as it is an instrumental. Along with "In Their Darkened Shrines I: Hall of Saurian Entombment", the lyrics are supplementary to the theme of the instrumental.
The two main melodies of "Unas Slayer Of The Gods" are a tribute to "Gothic Stone/The Well of Souls" by Candlemass, from their doom metal album Nightfall.
Music videos were made for "Execration Text" and "Sarcophagus".
