in this place seems to be in extreme disrepair, but are still working. Watchtowers and buildings are everywhere, and according to Dr. Tomlin, Matia seems to be a "prison zone" for the Argilans. Some god-like force exists here, in two forms: The "Wanderer" and the "Good Servant". There is much debate among which one could be a savior, and the other which could destroy everything. The topmost level houses a chain-link fence, a tablet open/closed by a wind-up key, and a dock for the Balloon. The middle level discloses two doors with watchtowers, and a track for a mine cart, above which lies a mound with dozens of watchtowers clustered like a termite mound. The bottommost level shows that the wall with doors and watchtowers is actually a massive hydroelectric buttress dam, with pipes and water valves here for maintenance. in addition, there is a room containing a small prison cell with a concrete floor covered with water from a pipe, its valve sabotaged so said floor cannot be indefinitely dry. In that prison cell lies Dr. Charles Santos, who claims to be on Tomlin's science team. Perched on a landing in this room is a device where two wooden cards can be placed, which, after moving its sliders, reveals the combination to the dam's maintenance doors. A village titled "Matiani" by Dr. Santos, reached by a strange double drawbridge, contains no people, but instead uses the entrances on each house as portals to shift dimensions, each, when demonstrated by the player, splits the veils of reality between Sam and Hannah bit by bit, until, by nightfall in completion, Sam/Hannah loses radio contact because he is now completely out of phase with him/her. A clue here is revealed by staring at the dam's top after shifting: Twelve lit towers in between the now lighted sentry posts in a unique pattern, requiring to be entered into the mechanical computer on Bosh. In the DVD version of the game, another village house which is larger than the others, perhaps a living quarters for the former guards, can be accessed from the main elevator, but its door is always locked. Behind the maintenance doors are two catwalks on the opposite sides with strange circuit boxes meant to raise sections of track. However, placing circuit links either horizontal or vertical activates automated markers at certain places meant to stop the player from doing so.
