Reborn Prosperity was the space station which was planned to succeed High Charity. While considerably smaller, it could still uphold a similar role; it began construction in 2560.
During the fight in and around the station in 2580, Reborn Prosperity (which at the time was only 44% complete), it was heavily damaged. It is theorized that the ill-equipped New Covenant likely salvaged it in order to finance the war effort.
