Ys

Once there was a mighty empire.   Now there are ruins.  There is something
wrong about the land.  It isn't in the scant and twisted vegetation, or in
the scavengers that roam.  It is not in the wind that blows, nor the pale
sun that shines above, but it is there.  Here the dead rest uneasily. 
Ravens and rats, vultures and wild dogs, these animals seem to be the only
inhabitants… yet something is moving.  Something that is never there when
you look at it.  Snatches of sound can be heard, garishly out of place
sounds, drinking songs, people laughing, children at play.  Sounds that
fade before they can be focused on or a location put to them.

The spirits of the dead of Ys seem to want to invade the minds of those who
visit.  Unless a careful mind shield is maintained, the spirits will become
visible in time.  You can have a pleasant conversation with a spirits who
believe themselves still alive and Ys still standing.  The ghosts look
whole and alive, and question your sanity.  Then moments latter the ghost
is gone… and it is you who wonder if you are going mad.  Sleeping in Ys is
something that should only be attempted within the protection of a mystic
circle.  People who have gone to Ys have vanished in the past with no
trace.

Biblographic Reference:  Read Ray Bradbury's short story Night Meeting from
The Martian Chronicles where an Earthman and a Martian argue over who is
the ghost or out of their right time.  That is how Ys feels.

The Cursed Pattern of Ys

The pattern of Ys appears to be a broken pattern similar to that of Kashfa
or Begma, but all around the pattern, the psychic residue of death and pain
radiate so strongly that even those without psychic sensitivity can feel
it.  The pattern can be walked, but if it offers any special powers, no one
remains to tell of them.  Walking the pattern of Ys seems to have one
additional affect.  The spirits become even more aggressive afterwards.
