Thank you! Yeah, it was supposed to be pretty open-ended. PCs might find it enough to simply explain the cause of the swords / draugr to the locals, or they might try to somehow seal the iceberg or prevent the eruption of the volcano. I do agree that it might be a bit too open-ended, though.
Another person said the same thing about Cursed Scroll; I have that zine but I never actually read it! I will have to do so. Please report back if you ever end up using this with CS!
