Spriggan mythology, mystical forest, ancient ruins, glowing mushrooms, twisted vines, eerie mist, moonlight filtering through treetops, a lone Spriggan warrior, horns and fur detailed, armor made of petrified wood, wielding a staff with glowing runes, powerful stance, one leg bent, standing on a moss-covered stone pedestal, surrounded by toadstools, eyes glowing with an otherworldly energy, misty atmosphere, cinematic composition, warm color palette, mystical ambient lighting.
