I don't know anything about dnd or pathfinder.<br/><br/>I think part of the cool thing about this world is the disconnect from the knowledge and traditions of established groups - so that can be used as a character goal to go out into the wider world to find those lost things. People know these things exist. It would be in the existing historical record and in oral storytelling. And those things that are known in the small world of the characters may not be quite what was imagined when found in the wider world! Think of the embellishment that would happen as people recall "the good old days" before the plague.<br/><br/>I have a lot of thoughts, but I'm at work. Mind dump coming soon!
