+## first-visit
+The conservatory roof has gone blind with moss and old rain. Vines press against the glass from both sides.
+
+Something human-shaped hangs among the ivy. The dining room is south.
+
+## revisit
+The conservatory sweats in the dark.
+
+## examined
+The tiled floor is split by roots. The air smells of wet soil and cold iron. Pruning shears lie half-buried beneath a bench.
