Enthralled by the beauty of Earth, Rose led her friends and allies in a rebellion against the Gem Homeworld around 5,500 years before the events of the series, successfully driving the invading Homeworld Gems off the planet and saving the life forms inhabiting it. Rose eventually developed a romantic relationship with a human, Greg Universe, before giving up her physical form to give birth to their son, Steven, who inherited her gemstone.
