The Tower of Light stood as a prominent feature of Zarra, which served as the capital city on the planet of Cato Neimoidia. This tower, a defining example of Neimoidian architectural style, provided a view of the Grand Theatre of Judgment. While on his mission to the planet in 22 BBY, Jedi Master Obi-Wan Kenobi concealed his lightsaber on the exterior of the Tower of Light, after Asajj Ventress, an agent of the Confederacy of Independent Systems, falsely implicated him in the Cadesura disaster.
