This adventure concludes the Quest for the Frozen Flame Adventure Path, a three-part monthly campaign in which the heroes lead a band of nomadic hunter-gatherers across a brutal primordial landscape. This adventure also includes a gazetteer of the mountain meeting grounds called Hillcross; megafauna animal companions and ancestral gear that complement the new Mammoth Lord character archetype; and new prehistoric creatures to befriend or bedevil your players.
