Pathfinder Adventure Path: Reign of Winter Part 2 - The Shackled Hut

The winter portal has closed, but the heroes now find themselves trapped in
the frozen land of Irrisen with an urgent quest - to find Baba Yaga! In
order to track down the missing Queen of Witches, the heroes must brave the
monster-infested capital city of Whitethrone, where Baba Yaga's Dancing Hut has
been captured and put on display. Will possession of the miraculous artifact
lead them to the Witch Queen, or will they die a cold death at the hands of
Irrisen's White Wtches?
A Pathfinder Roleplaying Game adventure for 4th-level characters,
The Shackled Hut continues the Reign of Winter Adventure Path, in
which players fight off a magical winter by venturing into the fabled hut of the
ancient witch Baba Yaga and trace her schemes across the worlds. This volume
also includes details on the goddess Milani the Everbloom, an article on the
ecology of the winter wolf, several new monsters, and new fiction in the
Pathfinder's Journal by Kevin Andrew Murphy.
