You sit on the baulk with Meg while the ditch runs properly, or at least better, and you explain a keep the way she explained fallow—from the road, which is the keep you actually have.

“Motte is a hill with a job,” you say. “Gatehouse thinks. Walls are work someone did with hands, palisade then stone. It is waiting for accounts, not a dragon. Kitchen is a mouth that never clocks off. Steward runs it more than any knight. Knights are landholders. Today they are at the shire, which is also work.”

Meg nods, then makes you name the strips until you can do it without her mouthing the words. She uses them as tools, not a song: winter wheat in the dark ridges, spring oats in the green, fallow with sheep, manure that will be bread, baulks between families, week-work on the demesne, hallmoot if you act like a shortcut is a road.

Neither of you wants to be a knight today. You want supper and a mill that hums and a ditch that remembers gravity. The keep on the motte looks, from here, like a kitchen with armor on.

A lark. A goose far off. Hew’s letter will go at a walking pace, which is a pace that leaves land alive.

THE END

What you learned: a castle is a hungry machine of well, stores, hall, and accounts; fields feed it through three-course rotation and tenant work. Knowing both sides—soil and solar—is the real map.
