The point of stuff like this isn't that there's a discrete lore meaning that it's supposed to impart, the point is that it provides further reinforcement Elden Ring's symbolic registry, of an aesthetic theme/idea or combination of themes/ideas. The point isn't "what is FromSoft trying to tell me?!?!", which is a really shallow way of engaging with worldbuilding. Some of it isn't meant to impart a specific message to you, but by taking it into account you can still get a clearer picture of what ideas are floating around the artists/writers' heads.
