A hyper-realistic, cinematic portrait of Professor Lydia Greyrose from Wizard101 as a real person. She is a petite, elderly fairy with a kind, grandmotherly face, soft wrinkles around her eyes, and pale, shimmering light-blue skin. Her hair is styled in voluminous, elegant silver-white curls, tucked under a wide-brimmed, pointed wizard hat made of rich blue velvet with silver snowflake embroidery. She wears delicate, thin-framed spectacles and a regal gown in shades of frost blue and crystalline white, featuring intricate lace and fur trim. She is standing inside the Ice School at Ravenwood; the background is a magical hall of carved ice and frozen crystals, with soft blue ambient lighting and magical snow particles floating in the air. 8k resolution, photorealistic, ethereal atmosphere, highly detailed textures, masterwork.
