The ring is constructed exactly 400 AU away from the star and is ten kilometers wide and one kilometer deep. The structure itself is made of an exotic metamaterial which has resisted all attempts to damage or dislodge it for further study. It is hypothesized that it is made of the same material as [[stories:mad:the_cube|The Cube]]. stories/mad/ienna_ringworld.txt Last modified: 2026/08/07 17:28by mecham
