Generate an enchanting and surreal depiction of a world locked in perpetual twilight. Picture a captivating landscape where the boundaries between day and night blur into an everlasting twilight. The sky should be a mesmerizing blend of deep blues and soft purples, with a faint, ethereal glow on the horizon. Show a mystical terrain, featuring delicate, bioluminescent flora and fauna that illuminate the landscape with gentle, otherworldly radiance. Let the scene emanate a sense of tranquility, mystery, and a touch of magic. Focus on intricate details and realism to create an image that transports viewers to this captivating twilight realm, in the style of Jean Giraud, in the style of Moebius.
