Imagine a massive planet where one half is covered in vibrant green forests, and the other half is a futuristic city filled with glass skyscrapers reflecting the sky. In the middle, a river of liquid light flows through the sky instead of the ground. On each bank of the river stands a giant creature--one made of the forest and the other of steel and technology. Both creatures extend their arms toward each other, while flocks of glowing birds circle around them in the twilight sky.
