Wyvern Above the Forsaken Fortress

A cinematic digital painting of a colossal wyvern perched along the crenellated ramparts of a centuries-old fortress at twilight. The wyvern's scales shimmer emerald and cobalt, with a serrated spine and vast wings folded along its body, eyes gleaming as it surveys the valley. The fortress rises with weathered stone, tall towers, an arched gate, and banners snapping in a cold wind. Torchlight along the battlements casts amber glows on stone and the dragon's scales, while distant torches reflect in a pale moat mist. A pale moon and wisps of fog backlight the scene, creating blue-pink and violet tones, high contrast shadows, and a dramatic atmosphere. Foreground rubble and creeping ivy add texture. Camera angle from a low, worm's-eye view emphasizes the wyvern's size and menace. The art style is crisp fantasy digital painting with meticulous detail on scales, stonework, and fabric, plus subtle glowing runes etched into the fortress walls. Color palette: deep blues and purples with warm golds and oranges; mood: epic, awe-inspiring, warlike.
