At some point, the Barsen'thor of the Jedi Order came to Belsavis to recruit an ancient species known as the Esh-kha. Unfortunately for the Jedi, the prison Warden, S. Geland, who was secretly a Child of the Emperor, used Belsavis' systems to try to stop the Jedi.
The Barsen'thor eventually came across the Custodian Droid, who detained the Jedi after being told by Geland that the Jedi was an escaped prisoner suffering from delusions. However, the Jedi Consular was able to prove their allegiance by lifting the droid. The droid apologized for his "Clerical Error", released the Jedi and also helped with sending all-clear signals. The Jedi later asked the droid if he knew about the Esh-kha, but he replied that he had no data.
