Design a dramatic and powerful landscape of the Fire Nation, inspired by Avatar: The Last Airbender. The scene is set on a volcanic island dominated by a towering, active volcano at the center, its peak releasing streams of smoke and glowing faintly with molten lava. The rugged terrain is covered in blackened, jagged rocks interspersed with patches of scorched earth. Rivers of glowing lava snake through the landscape, creating an intense, fiery contrast against the dark surroundings. Nestled into the terrain are majestic Fire Nation buildings, their architecture bold and symmetrical, with sharp spires and pagoda-like roofs. These structures are constructed from dark stone and adorned with flame-shaped golden accents and banners in red and black. A massive palace sits atop a cliff overlooking the scene, its towering walls and gates reinforced with intricate carvings of fire motifs. A bustling harbor lies in the background, where Fire Nation warships, sleek and menacing, are docked in calm waters that shimmer with fiery reflections from the lava and setting sun. The sky is an intense mix of reds and oranges, casting a fiery glow over the entire landscape. Smoke and heat waves rise into the air, creating an atmosphere of raw power, ambition, and control, embodying the essence of the Fire Nation.
