With Dorian keeping pace alongside me and Sean bringing up the rear, I lead the way into the kelp-covered ruins. The original walls were built of alternating, perpendicular layers of basalt pillars stacked on top of each other, each about ten feet thick and some up to thirty or forty feet high. Despite the rudimentary building method and the seeming primitiveness of this species, the work was nevertheless quite precise, with right-angled corners and leveled layers.
It takes a few minutes, but once he's exposed to more of what was once here, Sean warms to the explorations.
