You are in an air outflow duct above La Vie en Meow. It smells like croissants in here.
The file you are looking for is not here--sorry about that!
But the duct is not empty. Puck, a gray rat is here.
Puck looks up at you hopefully. He's been exploring the internet's HVAC system, and he seems to have gotten a bit lost. (It's a vast network, as you can imagine, with so many websites requiring a constant supply of clean, temperate air.) Will you please help Puck find his way back home? You can go left, right, or straight ahead.
