How do you assign a delve class to your delves? I expected the delve creation rules to have a method for assigning the delve class, but it does not. What factors should decide a delve's class?
When you roll for distance in markers, does this value represent total markers required to reach the farthest point from entrance or just raw markers distance downwards?
I've noticed quite a few of the PDFs referenced in the Core Rules aren't actually available on the downloads page; are those somewhere else, forthcoming, or just abandoned content? I can't find the trekking hex maps or a blank mission briefing template.
