I think it would be awesome if, upon hosting a funeral, you could pay extra to make the burial site a special landmark (where you can get extra exp and stuff during travels).
For instance, if my character created a new religion, upon his death, I think it would be fitting for there to be a grand cathedral created in his honor - a new landmark on the map that can be visited by future characters.
