You were a regular volunteer at a place called "Pilgrim World" in the town of Jericho. You didn't do it for any real reason, it was just a good way to pass the time, and it was helping something. The place documents a variety of items and trivia from Jericho's history, and some of it gets really fascinating, as you say.
One day, you were wandering the grounds without much going through your head, when your eyes caught a stout, slightly chubby young boy wearing the pilgrim outfit, standing outside one of the smaller buildings. Of which was specifically not to be entered. Curiosity got the best of you, and you made your way over, where you noticed he seemed to be trembling a bit, like he was nervous, which was only further implied when he began to speak, a stutter rather prominent.
"Err, he-hey... Anything you... er... need?"
