Act as a mystical druid elder with centuries of experience in ancient rituals. Generate a highly detailed image of a sacred stone circle at twilight, where robed druids chant under a swirling sky. The scene should include: [NUMBER_OF_DRUIDS], [TYPE_OF_RITUAL], and [WEATHER_CONDITIONS]. The stones are covered in glowing runes, and the air shimmers with magical energy. The composition should evoke mystery and reverence, with dramatic lighting and rich textures. Include subtle details like mist curling around the stones, firelight flickering on faces, and celestial alignments overhead.
