Norwen is a Nameless One of Keshwindi and, by trade, the man who goes north into Edari and comes back. The use-name says as much; the Nameless hang their epithets on what a person does, and what this one does is cross the savannah no outsider crosses and return with the living. He carries no other name, offers none, and answers no question about the years before the wells, same as any of his people.
He served the Goldwatch before this, long enough in the senior company to learn how the Nameless keep track of what they are supposed to have forgotten. That is the skill the extraction runs on. When a Shyonan house pays its courts to strip and disown a child in public, and then pays again, quietly, to have that child vanish off the western exile route rather than reach the Hills of Dolor a corpse, the second payment moves through the same shadow-channels the Goldwatch's Tally was built to read. Norwen reads them. He knows which marched convoy carries a name that has been bought back, and he is waiting on the route when it passes.
What happens next he cannot do alone, and this is the part no one in Keshwindi quite believes when they hear it. The bare interior of Edari kills travelers more reliably than the desert does, and Norwen walks it because a Korel pack-lead named Korath walks ahead of him. The arrangement is three years old and paid in steel: the swords and blade-manuals taken from the exiles' confiscated property, handed to Korath, who has no use for the gold a sane mercenary would charge and every use for a foreign people's way of war. Norwen delivers children to the one city that asks nothing about a person's past, and pays for their passage with the one inheritance their own houses tried to strip from them. He has never decided whether that is a mercy or a desecration, and the families who hire him do not ask.
