Before heading inside the meeting room, everyone in the team signed a non-betrayal Oath in the Village Center. And, as with others, the loyalty oath would be completely voluntary.
The oath was a standard perpetual non-betrayal oath made by Mathilda and Lawyer Jun to ensure there were no loopholes. This was something every territory employee, Terran or Aborigine, had to do before they get hired.
They would be given a choice to continue with the employment after seeing the oath, and so far no one had refused to do so.
At the same time, Altera wouldn't demand a loyalty oath asking for people's lives. Altera wanted to ensure its safety present and future, but didn't want to take away people's freedom.
