A thunderbird, its majestic wings adorned with glowing runes of power, takes flight over a mythical forest in a high-fantasy world. The wind whips through the trees as it creates a dynamic volumetric light show around itself. The vibrant magic aura envelops the creature, making its feathers shimmer with an otherworldly radiance. With each beat of its wings, the storm clouds gather and lightning dances across the sky, painting a cinematic fantasy art scene with intricate lore-inspired textures.
