Penyihir Badai Memanggil Kilat

A dramatic dark-fantasy portrait of an elderly wizard standing in a stormy barren wasteland under a black, cloud-choked sky. He wears a tall, weathered pointed hat with a brown leather band and a small metal clasp, and a heavy dark blue-gray robe with wide sleeves. His face is mostly obscured in shadow beneath the brim, revealing strands of glowing [electric blue] hair peeking out at the sides and a very long flowing silver-white beard reaching down his chest. The wizard thrusts his left hand forward toward the camera in a powerful forced-perspective pose with fingers spread, conjuring a bright orb of blue-white magical energy in his palm with crackling lightning arcs wrapping around his hand and sleeve. In his right arm he clutches a large ancient leather spellbook with worn corners, metal fittings, embossed arcane markings, and partially visible parchment pages. In the dark background, exactly one prominent lightning bolt strikes on the right side. Cinematic high-contrast lighting, sharp focus on the spellcasting hand and beard, gritty realistic fabric and skin textures, centered square composition.
