The Water Glyph Altar is a location found in the City. It houses the Water Glyph which manifests after providing water to the statue. Raziel needs to be able to swim to reach this area.
It´s only accessible via Water tower´s pipe and it leads into a small water reservoir with a waterfall. The altar itself is situated on the opposite side of the climbable wall. The far end of the room houses a statue of a woman with winged armour, the altar´s guardian. In order to awaken her, Raziel must venture behind this room and plug the whole with a pushable block. Once this is accomplished, the room is filled and the excess water will start flowing through a small opening and the statue will award Raziel with Water Glyph.
