RPG concept art of a hyper-realistic, imposing, fortified medieval castle with rugged, weathered stone walls, towering battlements, and majestic, Gothic-arched windows, situated atop a windswept, rocky hill, surrounded by a turbulent, mist-shrouded moat, a sturdy, wooden drawbridge, and a portcullis emblazoned with a regal, golden coat of arms, amidst a backdrop of rolling, verdant hills, dense, primeval forests, and a dramatic, stormy sky with rays of sunlight piercing through the clouds.
