When direction loses its certainty
Beyond the submerged cathedrals, depth stops behaving like a single direction. Circles, arches and corridors realign around Astra before she appears to change course.
A passage becomes a lens; a ruin resembles a calculation; the same structure offers another form when seen from another point. Perception is no longer separate from navigation.
As the structure realigns, Astra can no longer rely on a stable up, down or forward. The geometry is not merely surrounding the route—it is deciding what a route can be.
Is the geometry changing around Astra—or is Astra’s perception changing?
