Create a pixel anime art scene set at night, illuminated by a glowing full moon. Include a group of adventurers gathered around a crackling fire camp in the center. The fire should cast dynamic shadows and light, creating a warm, inviting glow amidst the cool tones of the night. Surround the adventurers with ancient, overgrown ruins, hinting at a forgotten civilization. The ruins should have intricate details like broken columns, scattered stones, and creeping vines. Add a sense of mystery and adventure with characters in diverse outfits, showing a mix of warriors, mages, and rogues. Use a color palette that contrasts the warm firelight with cool moonlit blues and greens, emphasizing the magical and mysterious atmosphere of the setting.
