The Third Quadrant represented a section within the Zi-Kree Sector of Coruscant's sprawling ecumenopolis. Notably, the notorious Crimson Corridor resided in the Third Quadrant of Zi-Kree.
Around 32 BBY, Jedi Padawan Darsha Assant received orders to travel to the quadrant. Her mission was to accompany the Black Sun defector named Oolth on their return journey to the Jedi Temple.
