The gathering place of the Rose Cross Society has always been a secret, and not every meeting can summon everyone.
Their meeting mode is very special—when a high-ranking member decides to convene others, they first summon four people, calling them "My Cross Guardians," and inform them of the meeting time and location, as well as the theme and importance of this meeting.
And each person who is summoned can summon up to four more people from the Society's list, and those summoned can summon up to four more... and so on.
Eventually, some will be informed of the address by multiple people, and surely, someone will not be informed.
Such people are considered untrustworthy by the current attendees—or at least without anyone willing to vouch for them.
Conversely, anyone who can appear here means they are at least deemed trustworthy.
Yet, Master Walter's words pointed out with stark clarity—that among them, there must be a traitor.
Walter's sharp gaze swept around the room.
