Create an illustration of a medieval-style fortress situated in a lush green forest area, replacing the existing castle's design with taller towers and arched windows. Adjust the color scheme to feature earth tones like browns and dark greens instead of grey and blue. Change the text label at the top to show a fictional name and number style without using any brand references, such as "Fortress ID: 123" and "Resources: 20". Ensure the background maintains a vibrant greenery with hexagonal patches.
