From publisher blurb:
A strange letter leads the adventurers down an unknown path as they answer a summons. One Ser Varkov has requested the party’s audience at his manor house, and it would have been rude not to accept. While the eskatari’s small and overgrown estate is unfamiliar, the journey is neither terrible nor dangerous for most of the ride. Then comes a tunnel and a trap, as a greedy knight lurks like a vulture. Now an important question arises: Can the might of the party bash through two nigh-immovable objects?
Through Stone and Steel On is a Q-Encounter, or Quick-Encounter, that can be run for a group of four to six players with 14th-level characters or higher. This encounter would be considered a ‘medium’ to ‘hard’ encounter.
