Tandis Four, situated within the bounds of the Galactic Republic, housed the Museum of Light. During the Clone Wars, and before the struggle for Drongar ended, the Separatists, acting under the command of Count Dooku, obliterated the museum. This event significantly damaged the morale of the Loyalist forces in that area, with Tannon Praji regarding it as Dooku's most heinous deed during the Clone Wars, and a barbaric action.
