Look up and to the left of the docking planks of Dock 07. There, on the top half of the Segment’s retaining wall, lies the Keyhole Passage. This passage is cut precisely into the rock face, and leads all the way through to the interior of the segment. Is this passage merely a convenient way in and out of the segment? Or is it perhaps something more?
One of Many
The Keyhole Passage above Dock 07 is by no means unique. Look closely enough at the exterior of the segment, and you will find one of these keyholes located above the site of each dock. What is even more interesting, is that these passages are present both above active docks, and those long-fallen into disrepair. This would suggest that they are an original feature of the segment itself, and not something added later on.
Essential for Production
In factory-held docks, the Keyhole Passages are used to transport people and goods between the docks and the segment interior. Many have set up elaborate elevator and pulley systems powered by crystals to further speed up and automate the journey. This simple shortcut handily avoids the long path through the dock itself and saves factories a great deal of time and effort.
Anatomy of the Keyhole Passage
The Passage itself is but a cleanly cut tunnel approximately seven feet tall by seven feet wide. It extends through the nearly fifteen feet of retaining wall, and then exits twenty feet above the floor of the segment.
Surrounding this passage is a series of strange, and equally precise cut outs in the rock face that surround it. These cut outs are much smaller in size and don’t seem to extend all the way through the wall. If something were intended to fit into the main passage, these slots would well positioned to assist in its alignment.
Each passage and its surrounding slots share standardized patterns and dimensions between one another. These striking similarities between them, as well as their purposeful positioning around the segment is curious. A simple short-cut through the retaining wall hardly seems vital enough to have been added to the segments during their design phase. What true role then, do these passages serve?
