Publisher's blurb: It has been a century since the immortal witch Baba Yaga last visited the world, and the hour draws nigh for her return. But when she fails to appear in the frozen realm of Irrisen to usher in its newest ruler, pockets of winter begin to grow throughout the Inner Sea region. After 1,400 years of perpetual winter, the icy curse of Irrisen is spreading! What links do these strange blizzards and swaths of wintry landscapes have with Irrisen, and is there any truth to the growing rumors that the Witch Queen Elvanna has taken full control of the realm? Can her plans for the Inner Sea be thwarted, or will the Reign of Winter engulf the world? The Reign of Winter Adventure Path begins in the southern nation of Taldor, but you can tailor it to begin anywhere in the Inner Sea region, for soon enough the adventurers will be traveling into the frozen north. This Adventure Path ventures to strange and distant realms, some of which are revealed for the first time in great detail. Each monthly full-color softcover Pathfinder Adventure Path volume contains an in-depth adventure scenario, stats for several new monsters, and support articles meant to give Game Masters additional material to expand their campaign. Pathfinder Adventure Path volumes use the Open Game License and work with both the Pathfinder RPG and the world’s oldest fantasy RPG.
