"I wish that I would meet a vampire." The stone glowed, causing Jon to close his eyes. When he opened them, he saw that he was no longer in his bedroom, but rather a dark and dank place. At first he thought it was a dungeon, but then as his eyes adjusted to the darkness, he saw that it was actually a sewer.
He crept along the side of the tunnel, trying to find someplace a little lighter so he could see better, but the darkness seemed to continue in every direction.
A few minutes later, he stopped. Somewhere near him, he heard someone breathing. He turned around and said "Hello?" But right as he said it, a blur of something black darted towards him and pushed him into the sewer water.
Any other time, Jon would be disgusted, finding himself bathing in sewer water. But at the moment, he was just trying to stay alive. He struggled free from the grasp of whomever (or whatever) had a hold of him and rose his head out of the water to breathe in some much-needed oxygen. But just as he was taking his breath, the same blur of black pushed him again, sending him right back into the dirty water. Jon kicked and flailed, but it was no use.
The last thing Jon saw before blacking out was the pale face of a man, dressed in black. His mouth was open, so Jon could clearly see his fangs. It was a vampire.
This was Jon's meeting, the one he wished for.
