Create a high-fantasy character portrait of Ragnar Bjornsson (Jormungandr), a formidable member of the Brotherhood of Shadows. He has a strong, angular face with a square, defined jawline. His skin is fair with a slight golden hue, and his severe facial features are authoritative. His intense green eyes have a reptilian glint, both hypnotic and terrifying, with a penetrating gaze. His long blond hair is often braided in traditional Viking styles, and his thick beard is well-groomed. Ragnar is extremely muscular and powerful, with a wide torso and strong limbs, exuding an intimidating and dominant presence. He wears leather and metal armor decorated with snake motifs, a wolf fur cloak, and rune-engraved bracers and belts. He is surrounded by an aura of dark, serpentine energy, sometimes manifesting as moving reptilian shadows with a dark green glow.
