"Domine Non Es Dignus" is Latin for "Lord, you are not worthy"; a statement which is repeated in the opening half of "The Oblivion Gene".

According to the album's liner notes, the distorted vomiting sounds in the opener "I Wish I Could Vomit Blood On You... ...People" are "actual vomit[ing]".

For years the band maintained they would never perform live. However, they played 2 gigs in December 2005. Whether these are the first of many or the only ones they will perform was unclear until the release of Eschaton when the band announced that they would return to the stage in the albums insert, shortly afterwards the band was confirmed for the 2007 edition of the Inferno Festival in Oslo.

Vocalist Attila Csihar (Mayhem, Aborym, Keep Of Kalessin, Tormentor) is a friend of the band and does guest vocals from time to time, and, in particular, on When Fire Rains Down From The Sky, Mankind Will Reap As It Has Sown and Eschaton.

The band originally started as a raw black metal band. With the release of Domine Non Es Dignus, they have shifted more towards a grindcore/black metal sound.

"Le Diabolique Est L'Ami Du Simplement Mal", from 2011 album Passion, loosely translates to "The Devil Is The Friend Of The Simply Bad".

The 2007 album, "Hell Is Empty and All the Devils Are Here" is a quote from the first act of William Shakespeare's "The Tempest".

On the same "Hell Is Empty and All the Devils Are Here" album, the track "Der Hölle Rache Kocht In Meinem Herzen" is German for "The Vengeance of Hell is Seething in My Heart." This is the official title of the "Queen of the Night's Aria" in Mozart's The Magic Flute.

"Bellum Omnium Contra Omnes" is Latin for "the war of all against all", which is described by philosopher Thomas Hobbes in the book Leviathan as the natural state of humanity.

On their 2003 album, "Domine Non Es Dignus", the title "Rage, Rage Against the Dying of the Light" comes from the Dylan Thomas poem "Do not go gentle into that good night", the title "Procreation of the Wretched" is a tribute to Celtic Frost and their track "Procreation of the Wicked" and the title "Revaluation of all Values" is the English title of Die Umwertung aller Werte, a work by Friedrich Nietzsche.

The sample "Drive Deeper the Thorn," (from the album Eschaton) at the start of "The Necrogeddon" is Sam Neill as Damien in the film Omen III: The Final Conflict. On the same album, the sample "Kill Everybody in the Whole World!" - from the intro of "The Destroying Angel" - is clipped from the British comedy series Blackadder II.

"Anaal Nathrakh" or "anál nathrach", comes from Merlin's Charm of Making in John Boorman's Excalibur (1981). Given Michael Everson's transcription, Anaal Nathrakh means "serpent's breath".
