+## first-visit
+Portraits line the walls, though none survive intact. Faces have been scratched away, smoked over, or softened by damp until they resemble each other by damage alone.
+
+The room feels nearer to the dining room than stone should allow.
+
+## revisit
+The ruined portraits keep their places.
+
+## examined
+Frames crowd both walls in uneven rows. A funeral veil hangs from one torn canvas. On a narrow lectern below it, a register lies open under a weight of dust.
