The hollow is not a palace. It is a dip between roots. You arrive however you arrived: running, humbled, carrying a peddler’s pack of almost-horns, or simply quiet. The hollow does not grade your entrance. It smells like leaf-mould, cold water, and the clean dust of old wood. Elves live here as forest neighbors with rules, not as decorations. You do not stare at their ears. You do not grab gifts. You wait to be offered a seat of packed earth.

Elder Briar’s hair is the color of last year’s bracken—the old elf who remembers when the mill road was a deer path. “The road,” they say, as if continuing a sentence from forty years ago, “was a deer path. Then it was a cart. Then it was a wall that moved.”

If you brought Voss’s collage, Briar looks once, snorts like a dry leaf, and sets it aside. A sea-tooth does not impress a forest. If you brought only muddy knees, that is also evidence.

Thorn of the hollow kneels and lifts a curtain of moss.

White threads web the soil, fine as hair, busy without bustle. “Under-song,” Thorn says. “Trees feed these threads sugar—the sun’s work, stored. The threads feed trees water and minerals they cannot reach. A trade. Our magic is keeping the trade uncut.” Thorn tastes a careful village-word. “Mycorrhiza. Same quiet city. Different name.”

You look until the threads stop being spooky and start being a city.

Briar’s rule for visitors: tell the mill the truth without turning the hollow into a tourist pit. Messenger, not trophy-guide.
