Slavic dark folk metal, heavy distorted guitars, driving blast beats, tribal percussion, haunting female operatic vocals, aggressive male death metal growls, cinematic atmosphere, epic scale. Begin with low ritual drums and distant bowed folk strings, then build into downtuned guitar riffs and relentless blast beats; alternate female operatic lead lines with male growled responses, layering both voices in a massive final chorus. Use raw earthy percussion, mournful folk melody, dramatic dynamic shifts, wide cinematic mix.
