Slaves of Sargon
Session 4: The Spirit Walker, Bhenkadra, tells the heroes that Tome is a deadly foe who has been plotting against them since the very beginning of the adventure. He advises the adventurers find the seer and kill him.
Session 7: Tome is found by the reservoir performing a ghastly ritual over the Minotaur city’s water supply. The tainted water will run into the city transforming the Minotaurs that drink it into feral bloodthirsty monsters. The heroes interrupt the ritual, lessening its potency and slay Tome on the water’s edge. As he dies, the Minotaur seer tells the companions that he and the Spiritwalker Bhenkadra hear the same voice.
