Walter and Reiko wordlessly join in. It is a two-hour trip as before from Fort Inevitable to the tower. The stone staircase that led up to the tower’s door is now nothing more than a rubble-strewn cliff. On the tower’s south side, a dirt path winds up the steep embankment to a pitch-black doorway. It was obliterated in an ancient time so as to now leave a 30-foot-tall escarpment in its place.

The footpath climbs up to a jagged hole in the side of the green glass tower. The light outside the tower does not penetrate into the building more than a few feet. Beyond that, it’s pitch black.

Now what?
