Create a detailed close-up portrait of Ragnar Bjornsson (Jormungandr). He has a strong, angular face with a square, defined jawline. His fair skin with a slight golden hue and severe, authoritative features are complemented by his intense green eyes, with a reptilian glint. His long blond hair, often braided in traditional Viking styles, and his thick, well-groomed beard add to his robust appearance. Add a subtle aura of dark, serpentine energy with a dark green glow around him to emphasize his connection with Jormungandr.
