Rust is orange

I woke up and I was really stiff. Not just tired-stiff, rusty-stiff. I looked at my wrist and it was covered in a dusty looking orange. This felt familier... But I wandered into town, and then I realized either I woke up after a few hours, or it was way early. I checked my wrist (there was a strange contraption with numbers on it--a clock?). It was 5 in the morning. Really early, and nothing would be open.

Too bad...I forgot what would clear this up. So I wandered around, not sure about what to do. I think I wandered all around town. It's pretty big too, with a river running through the middle of town, connecting at the top to a giant lake! But I was walking until I saw something.

It was absolutely huge! It was a big blue building, about three stories high with a giant tube reaching from one end to the other on the top. It stretched from one end of the river to the other, with a modern mill on the side. I ran up to it and knocked on the orange door. No one answered, but a little flap next to it opened, and out popped a tray with a mechanical mouse on it. It talked.
"Hello Stranger. You might know Professor J. or not. But please leave a message, or come back later."
It disappeared back into the slot and a red light went on above it. I didn't really want to leave a message, but I was curious...

Something strange is going on here. I was gonna leave a message, but I decided not to, so all I said was "Um...". Then the mouse appeared again and said "Welcome Ziana! Please enter." I tried the door but it was locked with an old-timey looking lock. I looked around, maybe for a key or something, nothing. But I did notice that my middle finger if I press it to my thumb turns into a key that fits. Seriously strange.
