Trader Katerina:
I am working as a trader now, but actually my expertise is collecting and trading jewels. I find rare jewels by asking favors of travelers like you and sell them at Giran or Aden. Not long ago, I heard that one can find precious jewels at the Elven Ruins of Talking Island. It is an elemental stone used by the Elven Mystics or something like that ...
Now that I think about it, the Elven Ruins may be too dangerous for you to go to. I was going to ask you to find me that jewel, but ... If you come across an opportunity later on to explore the Elven Ruins, please come to me. Then I will tell you in detail how to find the jewel there.
