Aqueduct

Aqueduct Base, sometimes called Aqueduct, was a part of a large water-tunnel system on Powai Nui that broke down. Later, it became the base for the natives of the island after Keelo formed his empire.

History
The Aqueduct was built long ago, and eventually broke.

After Keelo was transformed into a powerful Toa and began taking over the island, the native Toa, Turaga and Matoran escaped. They found the broken duct, named it Aqueduct, and settled into it. The escapees including Maroona, Arvos, Lewok, Salvina, and Corduk. Later, Lewok would be captured by the empire, and Detras and Shensii would move in.

Decsription
The Aqueduct is a long section of corrugated metal tubing, which was been split and crushed down in several places. Where it enters the ground there is a meeting area, and deeper inside are several separated sections which are used as sleeping quarters.

It, along with the rest of the water system, no longer functions and therefore water does not enter into the base.
