Right now it was encircling Akureyri, a big (population 1.1 million), newish (eighty-four years old) habitat constructed in the style known informally as the double barrel, historically known as the O’Neill Island Three type. It was two large cylinders, parallel to each other, rotating in opposite directions. Each was enshrouded in complexes of mirrors and other infrastructure. The mirrors were aimed at the sun, whose light was bounced through windowed strips on the cylinder walls to illuminate the landscapes within. But it was about six in the evening local time, and so those mirrors were gradually being feathered to simulate twilight. By using the varp to zoom in, Kath Two could have peered through the windows to see the farms, forests, waterways, and habitations inside Akureyri, but she knew generally what it would look like, so she remained zoomed-out for now.
