Solvunn is a religious hub. And in my experience on archeological sites, religion tends to bury history, literally. Myths and superstitions are made out of things that either didn't happen or are explainable another way. The Bible is chock full of examples, so I do wonder if somewhere under the shrines there might be more than meets the eye.

I do think something links us all, and not just the Singularity. It may be a large part, but a religion built up around it, not the other way 'round, which means there was something before.
