The album incorporates diverse instrumentation, including bagpipes and horns, and delves into Incan, Mayan, Slavic and Greek mythology. Rotting Christ frontman Sakis Tolis considered the album "a journey into the knowledge of ancient civilizations and into the occultism that is rising from the dark side of each one of them". However, Tolis said: “A deep dip into the occult knowledge of the past led me to create this album. I have no special message. I was tired of them. I just want you to make your escape from everyday life and trip with me into the past.”.
The Greek phrase "Κατά τον δαίμονα εαυτού" may be translated in several ways, including as "do what thou wilt", a quote associated with Aleister Crowley and Thelema. Sakis Tolis contended that this was the label's translation of the Greek phrase, and a more accurate translation is "true to your own spirit", which better fits the subject matter of the album.
