In my graphic novel "The Return to OZ", the great and powerful OZ is a benevolent space fairing being looking to terraform a dead planet into one that can sustain life. Finding a dead planet rich in minerals, he terraforms it, creates an atmosphere, and populates it with plants from local galaxies first then animals from neighboring solar systems, then finally he begins populating it with beings from other galaxies that he has encountered in his travels. He then creates a society, a culture by which all the different intelligent species can live in harmony by. While the locals at first wanted to revere him as a god, he is very adamant about the point that he didn't create them, he merely transplanted them there, and gave them a home where they can live in peace with each other. the locals refer to their new home as "the land of OZ" in honor of the being who put them there. The key you see him holding in the render is the key to his terraforming device. The key is made of a metal that bends and reshapes it's self into what ever device or tool that the holder needs at any given time. It also has the ability to change it's atomic composition from metals to ores, to plastic, etc... The "key" is a key point in the story. pun unintended.
