Read up on the starter's adventure this morning. It's not a miracle of modern roleplaying game design, but a solid ghost story without any Alienesque Body-Horror or Jump Scares and no big metaplot or cosmic horror.
Should be a good introduction to the subject matter and exactly what I imagined from the setting. And I like that Olaus has potential for later mysteries.
The only thing I unasure of is that the 'Dance of Dreams' is spread all over Upsala. That makes sense to lure members of the Society, but sounds wierd, knowing that it's more than three hours away by horse.
