"I understand," Cedric said softly as he found the barrel. "But I'm glad you followed through. We need more people like you out there."

Grinning, he simply reached out and tapped the correct barrel in a rhythm. One-two, one-two-three. Fortunately for him, he was not doused in vinegar and the lid swung open.

"It's a defence mechanism. We have to tap this barrel to reveal the tunnel. If you tap the wrong barrel or the rhythm is off, you'll be sprayed with vinegar. It's a bit of a crawl, but don't worry! It's bigger than it looks from the outside."

He started crawling through the stone corridor, gesturing for her to follow him.
