Trader Katerina:
Although I work as a merchant now, my specialty used to be collecting and dealing in jewels. I would ask travelers like you to obtain rare jewels, and I would sell them at Giran or Aden. A little while ago, I found some entertaining information while looking through some ancient documents at the School of Wizardry. The Stones of Water and Fire that were once used by the ancient Elf magicians could be found some place on this island. It was a long-abandoned place called the Elven Ruins. Sound interesting to you?
The Elven Ruins are much too dangerous for someone like me, but I'm sure you can handle it without a problem. If you bring back the jewels that I'm looking for from the ruins, I'll pay you generously. How about it?
Say that you'll do it.
