Editing The Machine (section)

===Insides===
The Engineers mainly prowl the mechanized sections of the machine.. 

It is still not clear if the ancient civilizations and their descendants are in anyway the creators of the machine, or are in fact anyway related to it. 

They of course have legends and stories, but these tales have yet to be backed up with hard evidence.

Inner oceans and rivers have been found, with piping that diverts the water to various parts of the machine...

Almost any surface environment's analog can be found inside of the machine and its caverns, along with entirely new ones, from a clockwork jungle, only called such because it if difficult to pass through all the working mechanical parts, to a frozen lake the size of Texas with an empty Ice City, it should be noted that this city is built on a scale completely wrong for humans, and is better suited to beings nearly twice as large.

There is an Empty Town, very near the first exploration point into the machine that is the starting base camp for most delvers. This city was the first to be picked clean of 

artifacts. It is now a watering hole literally, as there is a supply of fresh water being shipped in from the surface via complex piping.
