A striking poster of a powerful female Sith Lord from STAR WARS, set against a dark, ominous background with swirling red and black clouds. Her menacing, glowing red lightsaber is raised high, casting a sinister light on her fierce, determined expression. Her intricate, dark armor is adorned with sharp, elegant details. The Sith Lord's piercing eyes and flowing, shadowy cloak create an aura of intimidation and mystique. In the distance, a faint silhouette of a crumbling, ancient temple hints at the secrets of the dark side, enhancing the sense of foreboding and power she embodies.
