The Marvelous Carnival

While resting and recouperating in Dewbreak the adventurers are summoned to visit an old warlock who lives on the outskirts of Dewbreak. He explains that he hasn't been able to communicate with his patron for the past year and would like the group to go to the carnival which arrives in three days and investigate if they have any connection to the loss of communication with his patron. The carnival is under her oversight, and so they might know something concerning his patron.
