Whoops, my mistake, when the 5th d burials moved to Saqqara, they still used pyramids, but they were pretty crappy ones.
It just pisses me off that following generation removed stones from the older structures to build their crappy stuff. When we collapse, they’ll do the same here. The electrical and rail infrastructures will be looted for the metal. Well, the railroad can be used to make a great many quality swords.
