Create an ethereal, stormy being inspired by Slavic folklore – a Płanetnik. Its translucent, mist-like body merges with storm clouds, with glowing, lightning-like eyes. The figure emanates power and control over wind and weather, with an aura of swirling air and sparks of electricity crackling around it. Add subtle details like flowing, cloud-like limbs and a crown of thunderbolts, evoking both beauty and danger.
