The Blackhollow Trilogy is a custom adventure path for the Coyote and Crow RPG that begins with "Horror at Blackhollow Lodge," where the player characters are recruited to find a missing elder, Elder Kochoov. This first adventure takes them into the remote Valley of Blackhollow to battle mutated creatures and uncover a hidden laboratory run by the Keetoowagi Federation, culminating in a confrontation with a vengeful Wendigo spirit. The story continues in "Night of the Dead," where the party infiltrates a heavily-guarded Gats facility to gather evidence and avenge Elder Kochoov. This infiltration leads to a terrifying encounter with the Hiihangaziwag, the mastermind behind the experiments, and the shadowy Mazozoog he summons. Finally, in "The Dark," the party is on the run and must decipher stolen research to identify the true culprit, a rogue researcher named Elder Calian. With the help of a shaman, they enter "The Dark," a perilous dreamscape, to find and confront Elder Calian in his laboratory and put a permanent end to his monstrous creations.
