Written in Blood (2011)

From the publisher's website:

When the Decemvirate sends the PCs to the Viking city of Trollheim in the frigid northern Lands of the Linnorm Kings to deliver a package to an allied scholar there, the Pathfinders soon find themselves unwelcome visitors. Forced to navigate the rugged, isolated city and interact with the standoffish natives, can they deliver their cargo to its target, or will they find themselves exiled from the city... or worse?

Written in Blood is the first scenario in the three-part Shades of Ice campaign arc. It continues in Pathfinder Society Scenario #2-17: Shades of Ice-Part II: Exiles of Winter and concludes in Pathfinder Society Scenario #2-19: Shades of Ice-Part III: Keep of the Huskarl King. All three scenarios are intended to be played in order.

This scenario is designed for play in Pathfinder Society Organized Play, but can easily be adapted for use with any world. This scenario is compliant with the Open Game License (OGL) and is suitable for use with the Pathfinder Roleplaying Game.
