When the Tide Shifts

The Changing Tide is a group of people, all having one thing in common; we are , or we know, the secret that certain people are willing to kill for. That's why we choose our nights for meetings at random. There is no pattern that we can rely on, and it sometimes changes the day of the meeting. There are about 17 of us in total. For those of us that are the secret, once we begin showing symptoms, we receive a message. No one knows who the messages come from. We hear a voice in our head telling us somewhere to go and when, and, since we are all terrified about what's happening to us, we go. For those of us who aren't, it's simply discovered in another way, then the voice alerts us of meetings.
