An ancient oak tree stands silhouetted against a twilight sky, its gnarled branches reaching up towards a swirling vortex of stars and nebulae. The roots of the tree delve deep into the earth, intertwining with glowing crystals and ancient artifacts, drawing energy from the cosmos above. The scene is rendered in a 3D surreal style, with cosmic visuals and an intellectual tone, reminiscent of Alex Grey's visionary art and Max Ernst's dreamlike landscapes, bathed in ethereal luminescence.
