The group has several reasons to exist :
1- Find a safe place to talk about supernatural world and problems that goes with it.
2- Keep a watch on the group sector for any major non natural event in order to report it
3- Send a Mayday in case something is coming for group's member(s)
Wayne's uncle is your contact, he is not part of the group and will not interfere unless you ask him to, but it better be wrth.
So I leave you to share about your characters between yourselves, even though creation is not entirely finished.
