A striking poster of a powerful female Sith Lord from STAR WARS, draped in a dark, flowing cloak with intricate red and black patterns, her eyes glowing a menacing yellow. She wields a double-bladed lightsaber, its crimson blades casting an eerie glow. Her posture is confident and commanding, standing atop a rocky cliff on a storm-ridden planet, lightning illuminating the distant jagged peaks. Her hair is styled into intricate braids adorned with metallic cuffs, and her face bears ritualistic tattoos that reflect her formidable connection to the dark side. The background features an imposing Sith temple shrouded in mist, hinting at ancient secrets and a legacy of power.
