+# Room 20: Meadow
+
+This is a green meadowland transitional area filled with beautiful wildflowers. The room serves as a connector between the coastal cliffs to the west and other areas to the north, south, and east. It is a simple passage room with no interactive objects, NPCs, or special scripts - players simply pass through while traveling between locations.
