As for what people did, they have the ability to write their story, as mentioned here:

which may also lead to a statue (statue would of course not be appropriate for every character, i.e. Rufus and what he did, but in that case it could be some nasty story.)
(I wrote a ballad for the first ECDQ, but then decided I wasn't going to do it for everyone.
This ballad however, should be fairly one known as it's quite the story.)
