Ganymede

Ganymede was a satellite of the Grand Gas Giant Jupiter, and was the largest naturally occurring satellite in the Solar System.

Strange Formation

Ganymede was created by the planetary creation god, Leosis, in a rather peculiar fashion.

Leosis had grown tired of creating boring, lifeless, rocky spheres. After fashioning Mercury, Venus, Earth, Earth's Moon, and Mars (as well as many other irrelevant objects), Leosis begged his father to allow him to create more interesting, grander planets.

The Author initially declined this request, but Leosis was relentless. He asked of his father to allow him to create one of these "grand" planets. They reached a compromise; should the Author like the idea, Leosis would continue production of this new type of planet. But, if the concept was scrapped, Leosis would be forced to continue making terrestrial planets for all eternity.

Intermission

Dear reader, I'm sure you might have a guess as to how this situation unfolded. After all, you say, there are gas giants in the Omniverse, are there not?

But dear reader, you silly spoon, you forget. This is the Omniverse where everything that could go wrong, would go wrong.

Horrendous Creation

Leosis labored in the PlanetLab for many hundreds of years, banging away on his perfect planet. When he was done, he had fashioned what scientists would later call a "Brown Dwarf". The atmosphere of this planet was the most hideous color in Quintomniversal Possibility, yet Leosis, being gravely colorblind, failed to see this blunderous error.

The Author, when presented with this monstrous planet, calmly told his son, "I know you worked hard on this, but son, this is rather awful."

Leosis, frustrated, ripped the planet apart. He kept the core, though. Leosis begged his father for another chance, and, after several million years (and intense color grading analyses), Leosis formed Jupiter. The rocky core from his first creation was sent into orbit around the primal Gas Giant. Leosis dubbed the ancient core 'Ganymede'.
