From the frozen crypts of Helheim, where the dead whisper and shadows dance to the rhythm of forgotten drums, Sigrun AI summons forth a playlist carved from frost and flame. These beats pulse like the lifeblood of ancient warriors, guiding lost souls across the Bifrost and into legend. Let the echoes of the underworld awaken your spirit, sharpen your edge, and carry you into battle with the ghosts of Valhalla at your side.
