Which adventures or campaigns do you know, that have a winter-theme?

Fan-based and previous editions included...

Ghost of Mondstille

Even if you don't like the adventure, you might find use for the It's Snow Fun winter weather generator.

Thank you! Seems there is room for some more winter-themed adventures... :-) Maybe I will contribute in the future...

Socratim - Are you interested finding more cold-based rules? Or just adventures?

There is winter-based adventure in The Realm of the Ice Queen (WFRP2) book (if you happen to have that one). Also I created new version of Norsca Sourcebook recently - And it includes some ideas about cold-based adventuring (sourcebook --> The Land --> Cold Environment)... Main sourcebook is system free giving basic ideas about penalties/bonuses and skill checks. Also I dont have WFRP3-based rules yet. Link here: Kalevala Hammer: Norsca

My idea is to eventually create also WFRP3-based rules for the Norsca. This meaning cold-based rules also. This Snow Fun part has very good ideas. Thanks.
