I was feeling sorry for the poor guy man. Dang. Different. Making me think twice about that tattoo.
Great imagery. I was compelled and would love to know more about Dex.
You really did an excellent job in transporting the reader to some grimy dungeon of doom and infinite torture...while giving minimal descriptions! :) Very well written, though I think you intended to say "is its source...?" and not of "is it's source...?" (possessive, not contraction of "it is").
Please take a look at my drabble entries as well...I'd value your feedback. :)
Good luck!

Well I tried to take things I would fear in such a situation (not being able to see my surroundings or define the source of sounds) and use those elements in the setting that was so clear in my mind. Now that I think about it, a good inspiration for horror and torture is The Pit and the Pendulum by Edgar Allan Poe.
