When I GM the Mines of Kranak, I figure it'd be more fun for me to describe items based on whether or not a character would know what they are IC.
I guess it's the difference between me saying "You found a chunk of mysterious ore. It probably has special properties." and "X recognizes this ore as common, nonmagical iron."

So while we're [i]waiting on those next posts[/i], can I get a quick rundown of what everyone's likely to know about, based on their histories and occupation? It will save time rather than having me ask you last minute.

Off the top of my head, I'm especially considering stuff in relation to

-Geology
-Smithing
-History (Dwarven)
-Mythology (Dwarven)
-Culinary Arts (Dwarven)
-Wildlife (tundra/mountain climates)
-Mycology
