Surreal endless staircase twisting through the dark sky

picture a dizzying, Escher-esque staircase that spirals endlessly into the sky, with figures ascending and descending in a never-ending loop. The architecture is a blend of gothic and art nouveau, with intricate details and impossible angles. The scene is rendered in a surrealist style, reminiscent of M.C. Escher and H.R. Giger, with a color palette of deep blues, purples, and blacks, and a touch of ethereal mist adding atmosphere. digital art masterpiece. Best quality.
