Cavern of Light
Status Destroyed
Position Onu-Wahi

The Cavern of Light was a Lightstone mine in Onu-Wahi.


The main supply of Lightstones for the village of Onu-Koro was located here. Its entrance was located in a tunnel network connecting Onu-Koro to Ta-Koro and Le-Koro and the cave itself was only accessible when its entry was unlocked with a special key.

Shortly after the coming of the Toa Mata, the cavern was cut off by a rogue flow of lava. As a result, Lightstone productivity ground to a halt and Onu-Koro was forced to use torches instead, which proved ineffective against the threat of Rahi such as Kofo-Jaga. The wandering Av-Matoran Takua stumbled upon the Cavern and surfed the lava to reach the pump that controlled the flow using his Lavaboard. After he repaired a mechanism which pumped out the lava, the miners were then able to mine the Lightstones once again and light Onu-Koro.

Later, the Cavern of Light was destroyed by the reawakened Bohrok swarms.
