Places of the Lost Voices. I Need Help! (Possible Spoiler)

Well I :akimbo: and :rifle: and :minigun: my way though the The Big Dragon Cave (I don't know the name :-? sorry) And then I went back the The Universty Zoological Society, and picked the lock on the Ancient Safe (via Fate Point ) And Found the map to the Place of the Lost Voices. So I went there. And I have no clue what to do there. And What is with the "Drum-with-a-craving-of-a-book-on-it" thingy? Have I discovered some weird developer secret, or is that another on of those, lost-the-stupid-manuel-so-don't-know-what-to-do moments?

I'm a little confused, but I know that what you are supposed to do when you get to the place of lost voices, you then take thoes three cilinders and use them with the machine. The first time will activate a bunch of mechanical arachnids of some sort, then you can just put the rest in after they're dead. Then it'll tell you to look in the book of Durin's something or other, which is in the book case thing in Victor's house(Caladon)

 

If you do the cylinders in the corect order, then you can avoid releasing the 'nids. I think you use them in the order 'key' 'cypher' 'book'. Not too sure on that order though as it's been a while....
