The most placid of the regions of Mata Nui, Ga-Wahi is a large and mostly submerged area located on the eastern side of the island of the island. It is dominated by the great Naho Bay, which takes up the vast majority of the region and is surrounded by towering white cliffs. Ga-Wahi's landscape is very diverse, featuring sandy beaches and sharp cliffs, green strips of thick forest near the sea and wide grassy plains further inland. Ga-Koro is located in this Wahi, floating in the southern part of the bay at the delta of the Hura-Mafa River. Local landmarks include:
-Naho Bay: Bordered by pale cliffs, this wide cove is home to Ga-Koro, Ga-Kini, and Ga-Suva, as well as several underwater caves. A large waterfall pours into Naho Bay, and the rock face of the falls is sculpted into the likeness of a Kanohi Kaukau. There is a peaceful cave behind the roaring waters.
-Hura-Mafa River: This river runs northward from the slopes of Mount Ihu into Naho Bay, emptying there bay by means of the Naho Falls. It is one of the largest rivers on the island, and serves as a speedy ferry for trade from Ko-Koro to Ga-Koro.
-Old Fusa Path: This pathway was created by the Matoran to serve as an inland access point to the beaches of Naho Bay, and ultimately to the village of Ga-Koro. Harakeke and Bamboo plants proliferate along the path.
-The Dark Walk: One of six large tunnels dug by Makuta’s Rahkshi during the final days of his rule. Large enough to encompass a walking legion, it runs directly from the doorstep of the Koro down into Mangaia. Exudes a definite aura of odiousness, and is generally avoided.
Led by Akiri Hahli, Ga-Koro is built on huge lily pads, held in place by thick stems that grow underwater, with segmented leafy walkways and bridges connecting the platforms. It’s built around a central plaza that is faced by the Akiri’s hut; the plaza also doubles as the main marketplace of the Koro. Huts are made of more lily pads and look like cabbage heads, though they are very sturdy.
Since the village’s betrayal by the Toa “Arete,” Ga-Koro’s culture had changed. The village no longer suffers fools or false idols and is far more judicious in how they view strangers. Ga-Koro has also built up its defenses by constructing new floating “sea forts” for its Marines, the Koro’s guard service. The village gates are manned with twice the personnel as in the days of Makuta, and the chain of command has been cut down substantially to prevent anyone unsavory from gaining control where it should not be held.
But Ga-Koro’s creativity went beyond the martial. The Ga-Matoran have, with the help of Onu-Koro’s engineers, constructed several underwater greenhouses that grow food, plants both medicinal and industrial, and other cash crops. Strategically protected by Marine sea forts, these greenhouses are equipped with state of the art oxygen filtration systems and solar panels, not unlike those used by the miners in the Great Mine. Armed Toa and a lock system that is designed to fool all but the Onu-Matoran engineers who designed it defend the gardens from saboteurs.
Ga-Koro has largely detached itself from the squabbles of other villages, but its influence is still felt throughout Mata Nui: the Koro now supplies most of the island’s food and medicine, and if anything were to befall those greenhouses, the stock of supplies under the control of the Ga-Matoran would long outlast those of the other villages, making Ga-Koro a crucial ally to the other Koros.
