I was Googling one of my favorite level names from Marathon, "Where are
monsters in dreams", and found this link:

"As the wheels of the world carode in the heat of decay we must ask
ourselves, *where are monsters in dreams?* ..."
Could this book be where Bungie got the name?
Also of note:
"Iron demons of cold flame guarding eleven doors within 13 *pathways
into darkness* and hallways that dwell within the living stone here upon
the gates of eternity..."
Interesting...my apologies if this has been discovered already.
