gollark: Did you know? It was already too late. The bees had approached. GTech™ dominion over reality had begun, and none could escape. One night the bees reached the horizon of the sun, and all the specks began. The swarms of specks, all over the city, and even over the whole town. It would be next year that the bees reached the horizon on the night of December 14, 2011. After a week of resting they came to the end of October. They were too exhausted to continue their journey even upon midnight. In the morning they returned to the city to continue their "trip" that came along with the plague. The evening afternoon after dawn, they crossed to the eastern edge of the city, and began their journey on the night of December 15th. The next day, the bees went on their trip to the west of the city. They went on their journey along the northern coast with an aeroplane. When they arrived in the coast of the east of the city, they had a night sleep, as they had not come along the northern coast any further.
