Olfactory notes in depositions: salt, copper, wet stone, and organic sweetness like fruit fermenting in a closed room.
Historical Record
Size varies from dog to building in accounts.

Cross-links at dossier foot should be treated as hypotheses, not as family trees carved in stone.
Field Observations
Do not engage alone; do not accept hospitality from hosts who show windows to other eras.
Submit Form Theta-9 if conversation turns to cities remembered only in sleep.
