I highly recommend the Norrøngard Campaign Setting! It is such a fun setting that treats traditional Scandinavian folklore with such respect in a setting that feels entirely fresh, yet familiar enough to jump right in. The artwork is fantastic and the content is rich with lore. I have been gaming, both as a DM and a player, for almost 20 years and found the encounters to be fun, fresh, and entirely enjoyable! I would provide examples, but NO SPOILERS! Additionally, if you haven't, read Lou Ander's Thrones and Bones trilogy!
