From the back of the book:
At the end of the day you come upon a small country tavern near a dark forest; over the door is hung a wooden sign with a blue frog painted on it. You enter and ask the barman about the local gossip. He tells you that the local order of Red Robed Priests have been swarming over the countryside, questioning strangers. The accursed priests have been causing trouble, and their actions have hurt the tavern business. The barman also tells you that the new tavern owner is looking for a sword to hire.
Team up with Quartz the rock demon to recover the magic Blue Frog Amulet. The work is risky, the danger great - but the rewards are well worth the trouble! (Just watch out for those red robed priests...)
