This supplement for Frostgrave: Fantasy Wargames in the Frozen City provides a study of constructs, offering expanded rules for their creation, modification, and even re-animation. It examines enchanters' workshops, detailing new magic items and base modifications that aid in the animation process, and also includes a bestiary full of new constructs. Of course, much of the knowledge that was once lost still exists in the frozen ruins, so the book also features several scenarios set in the once-great factories where the art of construct creation reached its pinnacle.
