Illuminate a mysterious scene of a hooded alien shrouded in darkness, its otherworldly presence casting an eerie glow in the inky blackness of the night. The alien's elongated, slender fingers extend from the billowing sleeves of its iridescent, shimmering robe, hinting at an unearthly grace and dexterity. Its eyes, pools of shimmering darkness, gleam with a hypnotic intensity, reflecting the twinkling stars above like distant galaxies captured in a gaze. The hood obscures its features, leaving only a glimpse of a sharp, angular jawline and subtle, ethereal markings that adorn its smooth, grayish skin. A faint, otherworldly hum resonates in the air, sending shivers down the spine of any who dare to behold this enigmatic being in the dead of night.
