Overview
I could not verify Shadowed Valley as a canonical location in Ghost of Yōtei from the available evidence. The name does not appear in the reliable location, activity or walkthrough material I checked, and I found no official PlayStation or Sucker Punch source that identifies a base-game region, subarea, settlement, mission location or landmark with that exact name.
Because the requested guide requires verified boundaries, child areas, named directories, progression states and comprehensive coverage, writing a conventional article for Shadowed Valley would risk inventing a location or merging it with a different place.
