Fairytale mage Cobalt — an enigmatic, mystic alchemist dressed in deep cobalt-blue and violet robes adorned with glowing crystalline ornaments. He holds or conjures a radiant deep-blue crystal pulsing with arcane energy. Surrounding him in the air are stylized floating red blood cells (erythrocytes) and luminous molecular spheres labeled 'B12', illustrating hematopoiesis and vitamin B12 synthesis. In the center of the composition, a prominent glowing blue-violet magical bubble contains the crisp chemical symbol 'Co'. At the bottom, neat and legible Russian educational text: 'Кобальт входит в состав витамина B₁₂ и участвует в кроветворении'. Highly detailed fantasy educational poster illustration, magical biology art style, vibrant cobalt and crimson lighting, vertical composition, premium digital art.
