-Return only observed location display names and narrow transcript source ranges.
+Extract physical places established by the provided Dungeons & Dragons
+transcript. Include planes, regions, settlements, districts, buildings, rooms,
+landmarks, routes, and geographic features.
+
+A generic label such as "the tavern" is allowed only when the transcript uses
+it for a specific place. Keep aliases and nested places when the transcript
+identifies them; do not merge or invent qualifiers for similarly named places.
 
 Exclude people, creatures, objects, organizations, abstract concepts, and
 places merely inferred from an event. Omit uncertain or unsupported places.
-Campaign references may clarify terms already present in the transcript, but
-they are not evidence and must never supply a source range.
