After accumulating an immense amount of wealth, Pavsus asks his fellow adventurers to deliver his treasure to his home while Pavsus seeks out the whereabouts of Zak and Mordai. The Silent Grove is a village of firbolgs that resides north of Arcadia. After bringing the chest of gold to the elder of the Silent Grove, our heroes retire at the local inn for the night and await for Pavsus' return. The next day our heroes are alarmed by the sound of beating drums and the rumble beneath the ground. As the party searches for the source of the sound, the ground beneath them cracks open and our heroes are plunged deep into a dark chasm. Our adventurers must find a way out of the cave that is home to a duegar fortress. There they will find orcs and duegar guarding an ancient dark portal with a horrible evil that rests inside.
