So, on a planet just chock-full of paranoids, some of them are bound to
get together.  When they do, they wind up forming societies whose
purpose is explicitly to "find out the conspiracy" or "infiltrate Big
Brother's network" or what-have-you.  Normally, in these cases on
Asylum, either there's a warden in the germinal group (in which case
he makes sure that it goes nowhere), or one gets invited in before too
long (in which case, again, he kills the group subtly from within).
However, amidst this milieu, it was sort of inevitable that, after
sufficient time, such a group would arise, free of wardens, that had as
its prime directive the prevention of its own infiltration by
"outsiders," and only then the "infiltrate the conspiracy" directive.
Naturally, these arise only rarely, and usually their methods are not
adequate to detect and keep out the wardens.  However, in an infinite
universe, everything must happen, and even if the probability is small
of such a thing arising and surviving, an entire planet is a pretty big
place.  It happened in Thriff.  Such a society (let's call it Freemen
Exterminating the L.{{Large?}} Conspiracy of Heretics) arose, and
through its rules and customs {{oh, boy!  How are we going to manage
this?  How can they distiguish a warden or warden-lackey from a normal
guy, so they can keep themselves totally undetected by wardens?  do
wardens have different brain-scans?  Perhaps metal implanted in their
bodies (something no one in this society would have, due to insufficient
technology)? Other ideas?}} managed to go completely undetected by the
wardens.  Over the years, in pursuit of their secondary goal, they have
accumulated a fair mass of information about "the conspiracy," some of
which actually pertains to the wardens, and some of which is random-ish.
The real information they have mostly pertains to how to get in to the
Wardens' complex.  In order to get into the complex, one has to know the
location of the entrance (in the basement of Ye Olde Gasthaus), have the
key (every warden has one - note that the one held by Tinker is now in
the hands of a random thief-type scavenger or whomever that person gave
it to), and know the combination (every warden know this - or at least
how to figure it out on a given day - it changes).  FELCH has enough
information between the members to determine all of this stuff, though
they will have to figure out the location of the entrance (one puzzle),
obtain a key (could prove difficult, so we should probably give them a
lead as to who has it, or at least, who had it last...), and figure out
the combination (another puzzle).

**DP--Why is the information on how to figure out the combination available
in the first place?  Possibility:  the Great Wizard (now gone), being of
devious nature, decided to play one final trick on the wardens and slipped a
highly obscure reference to the door combination into the W.Guild puzzle-
chase.  This was subtle enough so that the wardens missed it, and somehow
FELCH either got or can get access to it.  (Maybe one of the FELCH-ers is
a wizard's guild member?)

**DP--Ah, but the Freemen, being *real* paranoid, have decided that
only people they know from birth and have kept track of are viable
candidates.  Therefore, since native wardens would have undergone a
suspicious "disappearance"(which may very well be a clue FELCH has) and 
return, they would be removed from the picture.  There are a couple of 
people here who qualify, although they are not being considered per se
(we just casually mention that so-and-so grew up with so-and-so and have
been close friends for years.)  That's how they'e kept themselves warden-free
this long.
