The painting on the cover was by Gunnar Silins, from a painting in the Royal Swedish Opera in Stockholm. The model used was Leif Ehrnborg, a then-top class Swedish bodybuilder.
The song "Woman of Dark Desires" is a tribute to the band's namesake, Elizabeth Báthory. "Enter the Eternal Fire" was the band's first epic, reaching nearly seven minutes in length, with lyrics referring to a deal with the Devil. The song "Equimanthorn" makes references to Hell as well as to Norse mythology, including Odin's "eight-legged black stallion" Sleipnir.
On the album's impact, Daniel Ekeroth, author of the book Swedish Death Metal, commented in an interview with Decibel magazine in 2012: "Even by Bathory's standards, this was a masterpiece, on par with both Bonded by Blood and Reign in Blood. The songs were perfected, and the sound more atmospheric and uncanny than before. Bathory were now the most extreme and one of the very best metal bands out there."
