The Jedi Citadel was a Jedi Citadel located on Koros Major. It was where the Jedi trained their younglings for war and from there that the Jedi coordinated their fleets and armies during times of war. Johun Othone and Tannis Venn died defending this Citadel from Zannah's Sith Order. The Jedi would later abandon this Citadel after the Sith attack and the Citadel was taken over by the Galactic Sentries who transformed it into a monitoring base and an Intelligence Center. A memorial for Johun Othone and Tannis Venn would be placed here at the behest of Drevint Varsallas.
