Tetrarch Talloth:
You've found all three materials. Well done! Now I can start my research to undo the 'spiritual chains.' We need further observation to see if the research will yield any results, but I believe that the seals placed on our patriarch will one day be broken. I will give you this as a token of my appreciation. Think of it as a just payment for working for our race.
I am not alone in the research to break the seal. Sorceress Kayla is continuing her research in the region known as Giran, to free the mental chains that bind the mind of our patriarch If you ever pass through that region, I suggest that you go and seek her. She may also need your help someday.
May the shelter of the abyss be with you, 'til the day our Dark Elf race rules the destiny of the land.
