Dead Sun - The large, abandoned human settlement building -Dawn-Region

On the deserted Dawn-region, there are many abandoned, ruined human settlements can be found, half-burried into sand. One settlement is still in-tact, and can be seen from far away on the wasteland. There is a large building in the middle of it, where people gathered, but as everything else, it is also in ruins: the roof collapsed, and sand covering the floor. The advena in white armor - nicknamed as The Silence -, sneaked into the building, and waiting to ambush. This is the area where the protagonist fights against him: the building is dark, and there is only some vague sunlight in the middle, coming inside through the collapsed roof.
