I settled down on a stone bench by the pavement, flag draped over my back like a sort of miniature cloak. Fatigue turned to slumber until I was woken up by a semi-distant rumble of machinery above. Looking up, I saw the giant metal freighter slowly crawl across the colourful sky, with another one in the distance flying parallel to it. Their appearance meant nothing - trading and logistics companies often used them to transport goods - but even so, they felt ominous and foreboding of something of a much bigger presence to come.
