There might be, but it isn't something we accounted for when putting in the plot request and so on (which I still have to get approved even though I'm a mod haha) so we don't have anything prepared! You're welcome to use maps or whatever found on bodies to have them figure out the information they're there to learn, like what passages the Ander Wardens already know about and use, but information beyond the scope of that would probably need to be a new plot request.
