[ As for the missing half of the party: one moment they stand among the ruins of a dreamed-up town. In the next, they're being yanked underground.
Everyone lands on their ass in a room of heavy stone. This is the Moss King's central chamber: goat-head statue, flames for its eyes, its great gaping mouth a doorway. There are adventuring packs tucked into the cubbies along the walls, waiting to be claimed. Further in, the walls don't seem to be stone at all, but a tight latticework press of a thousand million skeletons.
To the Nine Houses folks, it honestly feels like home. ]
