While the diminutive Bylur Frostfurr is well known to the residents of Einsmall as the best tracker in the North, the Vulpyne race has never been seen in Mythoss outside of that Far Northern settlement. Fleet of foot and with uncanny senses, Bylur immediately proves his value to the search for whatever is attacking Einsamall. Leading the party to the hidden lair of the Tundra Orc who is the main suspect in the brutal killings, the heroes uncover a monstrous secret and realize that their problem may be much larger than they had bargained for.
