Create a powerful and dramatic transformation scene where a human character transforms into a mighty entity, Vahlan. The human stands in the center of a dark, eerie cave, a flash of intense blue light begins to surround them. The camera zooms in as the transformation begins: the body enlarges, muscles swell, and shimmering blue energy engulfs them. Their skin shifts to a glowing blue, with sharp, otherworldly features emerging, including glowing eyes and a smooth angular face. Wings begin to unfold from their back with a slow, majestic movement. The ground trembles as the transformation reaches its peak, with blue energy radiating outward, leaving a glowing trail of light. The camera should capture every moment in slow-motion, emphasizing the intensity and majesty of the transformation. The scene should evoke a sense of power and awe, with intricate details of energy flowing through the body as the final form takes shape.
