Between 22 and 20 BBY during the Clone Wars, Jedi General Aayla Secura went on a mission to the facility to locacte a rumored secret in it. But she was stopped by Dark Acolyte and assassin Asajj Ventress. During their fighting, a beam that ran throughout the facility overheated, causing the facility to begin to crumble. Secura held back the debris and ordered many Geonosians stationed on the facility to escape through the tunnels of the facility.
