Frostgrave: Forgotten Pacts review

About Frostgrave: Forgotten Pacts, from BoardGameGeek:

In this supplement for Frostgrave, players lead their warbands into the northern reaches of the city, exploring the ruined temples of the Frozen City to search for the lost secrets of evocation--the art of summoning demons. While the lure of such knowledge is great, few wizards have ventured into this region as it is overrun by barbaric northern tribesmen, who have descended from the hills in their own search for treasure. Marking themselves with demonic sigils, many of these barbarians have aligned with ancient powers discovered among the temples. Along with a host of new scenarios focusing on the exploration of the temples, the book also contains new treasures, spells, soldiers, and creatures that can be found in and around the ruins.
