Epic Viking folk metalcore with a tragic, fate-driven atmosphere. Blend low-tuned guitars, pounding war drums, deep choir, bowed Nordic folk strings, frame drums, and distant war horns. Begin with a slow ritualistic intro, then build into fierce verses, extreme-vocal pre-choruses, and a powerful melodic chorus. Add crushing half-time breakdowns after the choruses, with choppy riffs, stomping rhythms, and gang shouts. The lyrics portray Ragnar Lodbrok as a saga figure: a warrior whose hunger for fame leads to a tragic death, while his name and choices live on through his sons. Invoke Odin, ravens, runes, fate, and the Norns. Make the mood grand but mournful, not celebratory. English lyrics, clear studio-quality production, original melody and arrangement.
