The Key to Freedom

The small brass key looks simple enough.. The only thing that seems to make it stand out are some words scratched into the head of it:

"Dark Iron Outhouse - Do Not Duplicate."

You have no idea what it means or what it will lead to.

*cough*

Who is it? Can't ya see I'm busy?

Well, I'll be! How in tarnation!? You found the key! I knew them blasted Dark Irons were hiding it after they locked me in here! Thank ya so much, <name>. You're the greatest! Now, just turn the key and let ol' Locheed outta here!
