The Hellfrost setting has a bunch of adventures for it (18 I think at the moment) several of which can be chained together. And while the adventures aren't on the level of Paizo's stuff, the Hellfrost setting itself is quite fantastic. In fact, I'm starting up a Rise of the Runelords game soon, but setting it in Hellfrost instead and using Savage Worlds. I was going to run it in Golarion, but simply use the magic rules from Hellfrost, but once I got reading Hellfrost again I remembered how awesome it is.
