A majestic marble hydra, fearsome and powerful, with multiple heads made entirely of smooth, polished marble. The hydra's surface features natural veining typical of marble, with a white base color and intricate gray, blue, and gold patterns running throughout its form. Each head is poised in a different direction, exuding a sense of relentless power and fury. The hydra's eyes are deep, hollow sockets that exude a sense of ancient terror and indestructibility. The hydra is coiled around a rugged, rocky mountain peak, the cold wind causing small flakes of snow to settle on its marble surface. The surrounding environment is a mix of sharp, jagged rocks and snow-covered terrain, with the sky glowing in twilight hues.
