Weird buildings theories?

I was wondering if anyone had any theories on what the strange building ruins could be. There are only a couple of them on SN's entire map, and they're all very hard to find, so it's pretty clear there's something both mysterious and important about them.

Perhaps they are connected to the energy pulse that destroyed your ship? Is it possible that the Warpers built them? If you have any ideas, please put them in the comments.
