In 14 ABY, it was reopened by the Disciples of Ragnos, who hoped to siphon the Force energy from the tomb in order to eventually reawaken Marka Ragnos, but they were halted by the timely arrival of Jaden Korr.
Korr eliminated the cultists in his way, and resealed the casket. Soon after though, the tomb began to collapse, forcing Korr to quickly escape the mausoleum. The tomb was sealed forever after the collapse.
