In Sword & Sorcery Northwind Tales, the heroes will journey to a land plagued by cold winds and snow, face a fearsome Viking army led by a conqueror named Wotan, find Yggdrasil, the tree that supports the universe, and face the threat of Níðhöggr, the undead dragon. The Northwind Tales Challenge Set expansion allows players to modify the game difficulty and the overall game experience by combining the S&S Northwind Tales enemies with new variants of all rank-and-file Enemies.
