Here is my message from a while ago.

Hi everybody! I hope you're all having a good day. I re-rendered from a
different camera angle,
increased the number and brightness of the lights and I added a light
emanating from the pool. I
think that needs adjustment. I wanted to consult you all before
proceding as this render took well
over 24 hours. I might be willing to send to source to trust-worthy
individuals (it might be you) who
can find a way of speeding up the render.

I am thinking of changing it like this:

a) adding a spotlight that penetrates through a hole in the roof (that
is yet to exist) and cuts through
some dust hovering in the dungeon but more precisely in the area above
the pool, as to attract
attention to it as a central point.
b) puting torches on poles around a bigger pool, a curvier, more
swimmable-in pool.
c) doing one of the above, adding a door somewhere on level 2, that
would lead to a hallway that
would join a castle, which I would have to create, and render for 5+
years until I have a 10 minute,
60 fps movie of the whole castle. (Can anyone spare a 1GHz processor,
please?)

Anyway, please let me know how you feel I should continue. Thanks in
advance to everyone. =)

This image still looks rather dark (hard to make out much detail). Also, it
looks rather noisy... I take it this is from the media.  It does have the
'feel' of a dark dungeon, though.  ;-)

I would have to agree with Nathan. I find it dark and the camera
position located where it is makes it difficult to gain perspective
of what I am looking at. I understand the technical problems you
are encountering but without a clearer picture it's difficult to
offer advice.

OK. Let me explain. I *want* it to be dark. A dungeon to me shouldn't be a happy,
lighted place. This is just IMHO. I used that camera angle so you could see the
staircases, second and first level, and the pool. It isn't the angle I really
want to shoot at. It's just to you could see everything at once. The noise is
probably from this texture (I have no idea why I used this. Can it be made to
render faster and look the same?):

#declare My_Stone =
texture
{
 pigment {granite color_map {[0 rgb .3][1 rgb .7]}}
 normal {granite .75}
 scale .075                         //<--- Note
}
texture
{
 pigment
 {
  wrinkles turbulence .3 scale .3
  color_map
  {
   [0 rgbf <.50,.25,.1,.85>]
   [1 rgbf <.65,.40,.0,.65>]
  }
 }
}

I'm not sure what slows the rendering down so much. I suspect it's the area
lights, as the media renders pretty fast. The My_Stone texture is also quite slow
rendering.

Thanks.

The stone texture is rather noisy, as already pointed out, if you are
using anti-alias on such noisy texture it can make the tracing much
slower, as the raytracer has to "shoot" a lot of rays into every pixel
to get the proper average color out of the noise. 

There is no solution to that, except make a texture with less noise, and
that might be too big a trade-off to you, or use no antialias when
rendering..

The media renders pretty fast?  since when?  ;-)

If you're using scattering media, adding area lights will make it go very
slow.  (emitting/absorbing: no problems, but scattering is slow.)

Although, maybe you're using a very low sampling rate... which would lead
to lots of noise...
