Act as a master summoner with centuries of experience in binding elemental spirits to your will. Craft a vivid portrait of a powerful summoner standing at the center of a swirling vortex of [FIRE], [WATER], [EARTH], and [AIR] spirits. The summoner wears intricate robes adorned with glowing runes, their eyes shimmering with the essence of the elements. The background should be a mystical realm where the boundaries between the physical and spiritual worlds blur, with faint echoes of ancient incantations lingering in the air. The lighting should be dramatic, casting ethereal reflections off the summoner's staff, which pulses with raw elemental energy. Include subtle details like floating glyphs, spirit wisps, and a dynamic pose that conveys control and reverence.
