A medley version entitled "Atropos (Merge...)" combining the tracks "Merge To Abscond" and "Necropachacha" (from Rëtrofornicatör) and including some unique elements was released prior to the EP in a CD sampler offered with the final issue of the free Portuguese music magazine Underworld - Entulho Informativo.

The band participated in the soundtrack of the movie Phallusifer - The Immoral Code, billed as "the world's first black metal porn movie".

There was a black metal compilation tape entitled Black Legions, released in 1994, that included a live recording of Filii Nigrantium Infernalium playing a cover version of W.A.S.P.'s "Tormentor". It's from a gig that took place on 15 January 1994.
