"A majestic, powerful black Pegasus stands firmly on a rocky terrain. The horse has a sleek, muscular build, with flowing, wild black mane and tail, full of movement as if caught in the wind. Its massive, dark wings are fully spread, with intricately detailed feathers that are both sharp and elegant. The Pegasus has glowing, intense red eyes that contrast sharply with its dark, glossy coat. The sky above is stormy and dramatic, filled with swirling clouds that evoke a sense of impending storm or magical energy. In the background, distant birds can be seen flying in the sky, adding depth to the scene. The overall atmosphere is mysterious, dark, and powerful, with a touch of fantasy and mythological grandeur."
