Northern Avistan has seen a lot of activity over the last couple of years. The Jade Regent Adventure Path took us through the Lands of the Linorm Kings and over the Crown of the World. And, the current Reign of Winter Adventure Path features Irrisen and the White Witches that rule there. Additionally, Paizo has published a variety of supplements supporting those APs.
Before all of these Kobold Press published a supplement with a different take on many of the same icy themes. Set in Midgard, Northlands covers Vikings, ice magic, monsters of Northern mythologies and the perils of adventuring in the cold. The book uses the Pathfinder rules, so its crunch is readily adoptable to Golarion. Additionally, I found the fluff inspirational as well. This is first of a series of blog posts detailing how I ported and extended the material in Northlands for my own campaign. The Wyrm Rhyme Saga, is a Viking dragon hunt set in the kingless Icemark region of Golarion.
