The Northern Lights which had drawn them from their childhood beds in lower latitudes on so many deep winter nights, while summoning in their parents obscure feelings of dread, could now be viewed up here at any time from within, at altitude, in heavenwide pulses of color, dense sheets and billows and colonnades of light and current, in transfiguration unceasing. In small, remote corners of the planet nobody was paying much attention to, between factions nobody knew much about, the undeclared and largely imperceptible war had been under way for years. All up and down the Northern latitudes, clandestine transmitters had been deployed amid pinnacles of ice, in abandoned mining works, in the secret courtyards of ancient Iron-Age fortresses, manned and unmanned, lonely and unearthly in the iceblink. On sky-piercing crags as likely to be frozen seabird guano as rock, scouts of Earth's Field, desperate, insomniac, interrogated horizons as to any signs of their relief, who were often years late. . . . And indeed for some, the Polar night would last forever--they would pass from the Earth amid unreportable splendor, the aurora in the sky raging up and down spectra visible and invisible. Souls bound to the planetary lines of force, swept pole to pole and through the fabled interior regions as well. . .
