Dialogue
 * "I have a theory about the plague, but I cannot be certain until I have performed some experiments. If you are still willing to help me, I would appreciate if (sic) you could travel back to Fahranur and gather spores from the insects that live there. I think they may have had more to do with the plague than I previously suspected. If you can get me at least 10 spores, I should have enough to perform my experiments."
