Estario grew up among the Rebels, showing a gift for invention from an early age. While others scoured the remnants of broken worlds for supplies, Estario spent his time collecting discarded technology, learning how to rebuild and repurpose it. His aptitude for engineering quickly set him apart, and by the time he was in his teens, he had already created devices that helped sustain the Rebel fleet. His most significant contribution came with the invention of hydrogen fuel cells, a breakthrough that allowed the Rebels to generate a renewable power source for their ships and outposts. This development marked a turning point in the faction’s journey, giving them independence from scavenged energy and enabling them to expand their reach throughout the galaxy. Estario’s work became the foundation upon which the Rebel fleet thrives today. Despite his pivotal role, Estario remained reclusive, spending much of his time alone in his workshop. He was known to go days—sometimes weeks—without emerging, his mind constantly occupied with new projects. Those closest to him knew that he was always thinking ahead, focused on pushing the boundaries of what the Rebels could achieve. While he seldom discussed his future plans, his contributions to the faction’s survival were enough to earn him the unwavering trust of his peers. His relentless drive to perfect his technology sometimes raised quiet questions about what else he might be working on behind closed doors. Whatever Estario is working on next, his contributions continue to shape the future of the Rebels, pushing the faction toward greater heights of survival and success.
