Great Mine

The Great Mine was a large cavern opposite the Le-Koro and Ta-Koro highways. It was the greatest mine ever and a work place for many Onu-Matoran, including Mamru, Taipu and an Onu-Matoran prospecter wearing a noble Matatu, named Azibo.

The Great Mine was flooded when the Gahlok invaded Onu-Koro. The flooding had a large economic effect on Onu-Koro.

The Great Mine was later abandoned once the Matoran returned to Metru Nui.
