Gnost-Dural was a Jedi Master and the keeper of the Jedi Archives. In the years following the Treaty of Coruscant, the Jedi Council tasked him with creating a new timeline of the event. His research during this time unearthed several unknown factors about the war and served as the basis for a new Jedi Library.
Gnost-Dural was inducted into the Jedi Order from birth, and spent his life training with his master until he reached the rank of Jedi Knight. For 30 years, he would train others and study knowledge of the Jedi Order until he was given the rank of Master.
Gnost-Dural was involved in an SIS project, codenamed "Endgame," which was a military and sabotage operation to destroy the Asendent's Spear, one of the last remaining creations of Darth Mekhis. He worked closely with SIS agent Tharan Shan and Republic Supreme Commander Jace Malcom.
