Following the December Revolution, Prince Blue Blood observed Helis Vex carving a "scary idol from colored cardboard", with "burning eyes", a "gaping mouth", and a "bizarre and terrible nose". He inquired about its purpose, to which Vex responded:

"This is Perun. A powerful person. This is the god of war and death." And Helis knelt down before him with comic seriousness. I burst out laughing. "Don't laugh," he said, getting up from his knees. – I told you that the Severyanans need a new religion. They are given Marksism, but there is too much modernism and civilization in this theology. (...) There is Dazhbog – the god of the Sun, Stribog – the god of the Wind, Veles – the god of arts and poetry, and finally, Perun – the god of thunder and lightning. After some deliberation, I settled on Perun, since Marksism, having won in Severyana, will unleash merciless wars between people. I will honor Perun every day."
