Aspa of Clandestine Blaze is most commonly cited as the vocalist. Hirilorn vocalist Shaxul stated that he was Deathspell Omega's vocalist until 2002, and has gone on record as leaving due to displeasure with the band's shift in themes. Early interviews were deeply critical of the black metal scene, and the last interview they agreed to until 2019 was conducted by their North American label The Ajna Offensive, with questions and answers sent through the band's exclusive label, Norma Evangelium Diaboli, to preserve their identity. In a 2018 interview with Loudwire, Tobias Forge, lead singer of the band Ghost, stated that the French synthwave artist Carpenter Brut (Franck Hueso) was Deathspell Omega's producer.

A month later, the band conducted its first interview in fifteen years with Niklas Göransson of the website and zine Bardo Methodology, during which they discussed the album's themes in detail. The band discussed a major impetus for the interview and the album being the Doomsday Clock being at two minutes to midnight, citing concerns over the degradation of the natural environment and the growing presence of authoritarian politics. They referenced Maximillien Aue, the villainous narrator of Jonathan Littell's novel The Kindly Ones, in discussing the narration style of the album, contrasting his perspective with Winston Smith's from George Orwell's Nineteen Eighty-Four.
