The Most Obscure Dungeon in RotMG

Today I found the most obscure dungeon in Realm of the Mad God. That dungeon is the Inner Workings, which a hidden extension to The Machine. It's password protected, so I have to go on a long journey across the Realm to find out how to get in...
You may have noticed the audio is a huge mess this time around. I don't know why that happened. Hopefully it won't be like that in the future. I did what I could to improve it (I actually dubbed the entire video over again) but it didn't completely solve whatever the issue is.
