Spiral of Atlantis
an excerpt

Morning over Tiral was always beautiful. As the sun rose over the horizon, it began to illuminate the earth below long before it touched the flying city; an observer could look down over glowing clouds and water while the city itself remained in complete darkness. Shigo Tillas loved it. He always made a point of rising shortly before sunrise.
Today he had been able to catch a hovertaxi to work, so he was earlier than usual. The man smiled slightly, pleased with this thought. The headquarters of TARO, the Tiral Aerial Resource Organization, were almost always empty this early. It would be nice to have a chance to slip quietly into his office, have a cup of coffee, and catch up on some work before the work day really began.
He was one of Tiral’s top engineers, and had become famous for his most recent series of inventions. Only a month before he had installed his new models of security equipment in the building. Now TARO security was state-of-the-art. The office building in front of him was not just impressive; it was literally one of the safest buildings on (or above) the Earth.
Shigo walked forward, preparing to enter his pass code into the side of the mirrored glass doors. The atrium wouldn’t be open this early. But today, something was off. Before he reached the key pad, the glass doors slid open automatically to admit him. And there were far too many people in there.
He could already feel his peaceful morning slipping away. Resigned, he entered the building slowly, the glass doors sliding shut behind him. For a few minutes he just stood there, unnoticed in the general hubbub.
