Each PC is a member of the Denny Society. The Denny society in modern times is a social group who’s purpose is protect the city of Seattle from the various supernatural threats that it might otherwise succumb to. More detailed information on the society can be found in the main article.
On April 30th, 2011, Lucas Maloof discovered a small collection of pages in his grandfather’s effects. These pages appear to be a journal entry, in Lucas’ own hand, describing a secret door in Denny Hall, and the events surrounding his meeting all of the other PCs. The pages are dated May 23rd, 2012. After finding the secret door leading to the Denny Hall Sanctuary, Lucas found each of the other PCs over the next several months, and reformed the society, which appears to have no other members.
It is clear that over the years, Seattle would have fallen many times over, if not for the efforts of the former society members. Many of the interventions the society has made, however, were stopgap and hastily made, and thus there are many weak points in the city that an enterprising individual might hope to exploit.
