An intricate illustration on aged parchment depicts the recipe for the "Elixir of Eternal Night." The detailed artwork includes demonic plants with thorny vines and glowing, sinister flowers. Sketched around the edges are occult symbols and runes. The recipe lists ingredients like "Essence of Shadow," "Nightshade Berries," and "Bat's Blood." Muted colors and scratches on the parchment add to the ancient, mystical feel of the illustration.
