Key's Note

This item binds when picked up

The note is written in mud.
"Goblins' approach is blunt but effective. They caught me and took everything (well, basically, everything that I didn't have time to hide. I left behind the most valuable stuff!). Threw me in here to die. They never learned how to tie knots or make locks, though. I don't know who will find my note. My messenger is obviously too soft and cowardly to get here. Whoever you are (not a goblin, I'm sure, they don't know how to read), follow me into the thing where everything is big, and small, and big. It's a long story, but someone told SOMETHING in my dream! And don't worry, I'll get back to the messenger later."
