Design a breathtaking and imposing scene of the Shadow Nation army in formation, inspired by Avatar: The Last Airbender. The image should depict a vast, nearly endless army stretching across a desolate, storm-lashed battlefield. The soldiers are clad in dark, angular armor with black and silver accents, adorned with shadowy symbols, and their faces obscured by menacing masks. They hold a variety of weapons—blackened spears, curved swords, and longbows—poised in synchronized readiness. The soldiers should be spaced apart in perfect formation, allowing a sense of vastness and depth in the composition, with enough room to eventually place a commanding leader figure at the forefront. This is not just one regiment but a colossal force, composed of multiple divisions spread across the battlefield. The frontlines feature elite shadow warriors in tightly arranged rows, while the ranks thin out as they stretch toward the horizon, displaying an overwhelming number of troops. The army’s immense scale fills the scene, stretching from one end of the battlefield to the other. In the foreground, massive war machines and siege engines—constructed from blackened metal and dark magic—loom ominously, their angular forms designed for destruction. These war machines are equipped with powerful weapons such as catapults, ballistae, and flamethrowers, ready for the impending assault. Dark banners emblazoned with the sigils of the Shadow Nation flutter violently in the wind, a grim testament to their power and unity. Above, the sky is not just stormy but filled with mysterious, swirling plasma storms. The atmosphere is charged with crackling energy, as streaks of vibrant purple, electric blue, and glowing orange plasma surge across the sky in chaotic, mesmerizing patterns. The storms pulse with dark energy, casting an eerie, unnatural light over the army, as if the very atmosphere is alive with ominous power. Occasional flashes of lightning arc across the sky, adding to the sense of impending doom. The plasma storms reflect the power and destruction of the Shadow Nation, as though nature itself is bending to their will. In the background, colossal warships appear as dark silhouettes against the plasma-filled sky, their sails black and billowing as they prepare for their own assault. Massive cliffs and jagged rock formations stretch across the horizon, with statues of warriors and leaders etched into the stone faces of the mountains, overseeing the army’s movements. The soldiers, while numerous, are spaced sufficiently to emphasize the scale of the army. This provides room to place the leader of the Shadow Nation—a towering figure draped in regal dark armor—standing on a raised platform or high atop a cliff, surveying the battlefield below. The leader’s commanding presence looms over the army, their gaze cold and calculating, ready to unleash their power on the world below. The overall scene is one of unrelenting force, dark energy, and the inevitable march of the Shadow Nation towards conquest.
