A striking poster depicting a formidable female Sith Lord from the STAR WARS universe, with intense red and black hues dominating the scene. Her piercing yellow eyes and intricate facial markings convey an aura of menace and power. She stands confidently, wielding a double-bladed crimson lightsaber, its glow casting sharp shadows. Her dark robes billow around her, intricately designed with Sith emblems and a hint of dark silver armor. In the background, a lightning-streaked sky over a desolate alien landscape adds to the dramatic atmosphere, with remnants of an ancient Sith temple looming ominously.
