Ronin of the Down-Draft Foundry-Crane Walk — an age of a great iron shipyard where the whole day's forged hull-plates ride out over the slip on one overhead crane-gantry, and the gantry's single steel catwalk runs directly beneath the crane's slung load through a permanent roaring column of down-draft where the cold sea-air is dragged down the hull's steel face and funneled through the walk; the Gantry-Ronin is the masterless blade sworn to hold the mid-catwalk mark through the whole lift, planted where the down-draft hammers hardest, not to guide the load and not to stop it, only to REMAIN on the mark so the crane-callers can read the true set of the swing off the line of her braced body — while every ton of iron overhead and every gust down the hull wants to fold her off the grating and drop her to the slip below
