a steel held breath that hides entire cities of men beneath the crushing dark
means A watercraft designed to operate underwater, especially a warship that travels and attacks while submerged.
from From Latin 'sub' (under) and 'marinus' (of the sea, from 'mare,' the sea) — literally 'under-sea.' English used 'submarine' as an adjective for undersea things from the early 1600s; it hardened into a noun for the vessel itself in the late 19th century, as inventors finally built craft that could dive, hide, and surface at will. The same 'mare' still tides through 'marine,' 'mariner,' and 'maritime.'
