The whole thread is illuminating to say the least, you can learn a lot about the characters here, and makes for great reading but one post, and one line and it's implications above all, just jumped off the screen and took my imagination hostage.

"Can one purchase this substance? I have a little bit of money I could sacrifice."

The word 'sacrifice' being key here. It is such a very Acolyte thing to think. Whether it's faith or madness is probably best left to the reader to determine but I found it worth a mention.
