An enormous, ancient tree at the edge of a precipice, its roots twisting down the rocky cliffside, with a glowing portal nestled within its trunk. The portal pulses with a soft, otherworldly light, hinting at an alien landscape beyond. A pair of adventurers, silhouetted against the twilight sky, cautiously approach, their figures dwarfed by the immense scale of the tree. Above, a swirling vortex of stars and galaxies slowly rotates, casting ethereal shadows on the ground. The air is filled with a sense of discovery, magic, and the unknown.
