Umbra and Protodax's Chamber was one of the many chambers one had to go through down the Staircase to the Ignika to reach the Chamber of Life.

The Toa Inika came into the chamber and found Protodax in their way. The Inika would have fought it until the Protodax was destroyed by the other guardian, named Umbra. He was eventually defeated by the Inika, for they used his powers against him.

It is unknown what became of the chamber after Voya Nui fell back into the Southern Continent, after Mata Nui rose, or when Teridax died.
