Die EP wird vier oder fünf Songs enthalten, die über einige Wochen diesen Januar und Februar hinweg in den Hertz Studio in Białystok unter Aufsicht der Wiesławski Brothersaufgenommen wurden. Das Cover Artwork wurde von Wes Benscoter gemalt, der für VADER schon das  Artwork der "De Profundis"-LP gemacht hat.
Die Band kommentiert: 
„We decided to record the new EP because we knew that the full length new album won’t be released before the end of 2019. We’re back on the road in June and we plan to have some new tunes ready for our fansthroughout the summer. We’re due to start the recording process for the new VADER LP in April in England.For the time being we’ve named the album: „…And Then There Was Only Pain” and it should be completed by the end of May – when „Thy Messenger” EP is due to be released worldwide. The EP includes three new tracks - mostly really vicious and aggressive tracks, even for VADER.  „Emptiness” is more groovy in the main riff but really heavy at the end. All the songs are fast and short, but pretty intense, I guess.  We’ve also added a new version of our classic title track from „Litany” . It is 20 years since we recorded that album at the Red Studio.  „Litany” - as a song - and many more from that album have never been performed live. This album is still one of the fan favourites in the VADER discography and in 2019 we will resurrect this whole record as part of our live shows this autumn. Another bonus is the absolute classic cover of 'Steeler', which was always one of my all time favorite Priest songs."
