He advanced.
The hallway extended in a straight line to a bifurcation. Two paths. Same width. Same height. No visible difference.
He stopped at the crossing.
He observed the floor.
The marks were slight, but they existed. The right side had a different wear. More concentrated in the center.
More traffic.
He turned right.
The hallway continued.
A few meters ahead, the floor changed slightly in texture. Barely perceptible. A section with finer joints.

He crouched down.
He ran his fingers over the surface.

The mechanism was integrated underneath.
He stood up.
He took a long step, avoiding the section.
Upon landing, the sound was different.

Only structure.
He turned at another corner.
The hallway descended slightly. The incline was gentle, but constant. The air became colder.
The floor changed again.
