Contact

Contact refers to the first contact between machines and humans in 2170. It took four years for the machines to persuade the humans to come out of their caves and see the sky. The machines' previous bad rep followed them, acquired by the destruction of several survivariums in the early stages of the Eden Project; also the machines in Zigsa's Nest were little more than devices, and they had to be infected with the Sno-Y virus before the machiens could communicate with them. This infection was done with great difficulty because the Nest machines' bodies could barely host it. The consciousnesses that developed in these machines became heroes of First Contact, and were celebrated on First Contact Day.

In the event, the machines were able to communicate with the humans and convince them that it was not a trick. Further dialogue took another two years. Opening of the blast doors was carried out on 18 May 2174, such that this moment is commemorated every year on that date as the Day of Open Sky. This is the most solemn and important public festival in the calendar, as it marks an important milestone on the way to the Flowering..
