The middle-aged planet Sol III was listed in the Register as an unremarkable garden world, where life had been developing with little interference for the past 3.5 billion years. There had been some indigenous sentient species of the reptilian, but they were kept under hibernation by the planet's goddess Gaea, who favored mammals as the dominant life form. Occasionally beings from the far more advanced planet Mars came by, but they preferred to leave it alone. Only a very few beings in the universe were aware that one day, the planet would be home to one of the most powerful species in the galaxy.
