Ashina Castle
Sekiro has no in-game map, so this one is drawn from above using the area's own level geometry. Open a marker for its vitality and posture, drops, boss rewards, what a merchant sells, or the travel menu's picture of an idol.
How this works: the terrain and buildings are rendered top-down from the area's map pieces, each painted in the average colour of its own texture, and every marker comes from the same map files, so both share exact coordinates. Things indoors or underground are also shown in the Below view, which cuts away the roof or rock above them.
How we checked it
Each marker is measured against the area's own geometry (map pieces, placed objects and foliage) at its exact position. 358 of 358 markers sit within 1 m of a surface, 334 within 10 cm. Measured straight down or up only, ignoring walls and branches: 305 of 358.Sculptor's Idols share the geometry's coordinates, so they line up exactly by construction. Ambient wildlife is left off; swimming creatures and scripted spawns are marked as such.
