The Ancients also created a ringworld in the Leenitakot system of the Hinterworlds. Even their approach to building a ringworld puzzles the experts. It circles a dim M1V star at less than 30 million kilometers. The ringworld is a narrow band less than 100,000 kilometers wide, and the construction looks unfinished, without soils, atmosphere, or any provision for life to live on its inner surface. And even so, this small ringworld has an inner surface area equal to 25,000 Terras.
