Po-Wahi is the Stone region on Mata Nui, located in a large desert with many canyons. The desert is a large, rocky expanse, located near the north of Mata Nui. It consists mainly of the Motara Desert, canyons, plateaus, and rocks. The area has a coastline as well, where Leva Bay is situated. Paths leading to Onu-Wahi, Po-Koro, and the Quarry could also be found here. Local landmarks include:
-Motara Desert: A desert covering the vast eastern portion of Po-Wahi.
-Tiro Canyon: A large canyon in Po-Wahi.
-Leva Bay: A bay located off the northern coast of Po-Wahi. The coastal settlement of Ostia is located here.
-The Po-Wahi Quarry: A large, canyon-enclosed area of Po-Wahi, it is here that the Po-Matoran mine stone for their famous carvings. In it can be found six large statues of the First Toa’s Kanohi, and these statues serve as doorways to the various sections of the quarry, unlocked by means of small keys emblazoned with the symbols of the Elements.
-The Path of Prophecies: A road flanked by carvings, leading to the village of Po-Koro, created by the Po-Matoran Carver Hafu soon after the Matoran established the village of Po-Koro. At the road's end is the entrance to Po-Koro, which is carved into the mouth of a large Matoran head.
-Forsi: A Sentinel-run port settlement on the Po-Wahi coast, this is also the outlet of the “Iron Mahi” locomotive’s track and a radio station.
-Ostia: A walled port settlement on Leva Bay. Caravans travel frequently between Po-Koro and Ostia, and travelers can usually join a caravan of merchants for relatively safe passage.
-Blackrock: An old fortress of the Brotherhood of Ak’rei’an. In the past, a combined force of Ga-Koro Marines and Po-Koro Sentinels drove the Brotherhood from this place. Battle damages, as well as sandstorms and stone pilferers, reduced the dormant Blackrock to ruins. After being eradicated from Darkmine in Onu-Wahi, though, the Brotherhood has returned to Blackrock and started to reconstruct the crumbling place.
-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. Akiri Hewkii has done his best to cover the entrance by walling it in and assigning guards to the hole.
Led by Akiri Hewkii, Po-Koro lays nestled in a canyon valley in the northern part of the desert. It consists of a village set within the confines of thick, masterly crafted walls of stone. A grand gateway and the short road leading to it define Po-Koro’s single entrance. Inside the village, simple stone domes serve as huts, shops and inns, several new structures hug the village walls, and a central marketplace hosts a continual bazaar. Po-Koro maintains its reputation as the sports capital of the island, and has the best Kohlii stadium and teams.
Most roads that once existed in the wastes are now scrubbed away. Already experts at traversing the vast wasteland, Po-Matoran are uninhibited by the lack of directional markers, and rarely get lost. Specially appointed patrols cross the desert, some tours to ensure the security of the Koro and others as essential traders. The old sand paths, though, have been replaced with a much more efficient method of reaching Po-Koro: the “Iron Mahi” locomotive. Designed by Onu-Koronan engineers, the tracks of this locomotive run from the coastal settlement of Forsi directly to the Koro. The Iron Mahi takes cargo as well as passengers between its two stops once a day.
For keeping in contact within their own kind even when they are across the desert, the Po-Matoran use a large, primitive radio communicator situated atop the walls of Po-Koro. From this transmission point, special messages in Po-Koro can be sent through the air to other such radio outposts elsewhere in the desert. The communication signals are always shaky, leading to easy misinterpretations, the range isn’t good, and the apparatuses are extremely vulnerable; but, even so, the solar-powered transmitters give the Po-Matoran the ability to respond quickly to disasters.
