A photorealistic image of the Ancient Oak of Knowledge in a forest clearing during sunset. The massive, gnarled tree is surrounded by a mystical atmosphere at night with the moons lightrays filtering through the branches and illuminating the scene. Glowworms hover around the tree, casting a gentle, otherworldly light. The air is filled with a magical haze, with swirling vortices of purple mana visible in the mist, adding to the enchanting ambiance. The setting is serene yet awe-inspiring, capturing the tree's ancient wisdom and mystical power.
