We have all seen gravestones after people have died, but from a Lore perspective I've always seen this as a little odd. Where does the stone for a "gravestone" come from? What chiseled your name on it? Why does it disappear if you pray at it?
Or more fundamentally, is a gravestone merely a game-engine artifact? Perhaps it's really a mark that people attuned to bindstones can recognize, knowing that someone died at this spot?
Whatever it is, I think it would be interesting to hear as to what the actual specifics of gravestones are. What someone who sees one actually sees. Presently, although the Soul Mother and Bindstones are well defined, they don't seem to have an in-world explanation and description anywhere I can find in the Lore.
