Trader Kunai:
I appreciate your willingness to help our Duda-Mara tribe. There is much to do, so I will tell you about the mission without further delay.
To discover the reason for this disaster, we require a medium. Once the Kasha Spider was our sacred symbol, and even though it has now been corrupted by this fiend, it will still be a suitable medium.
You can find the spiders in the north of the Immortal Plateau. Take the lives of the Kasha Spider, Kasha Fang Spider and Kasha Blade Spider and bring us 30 Contaminated Kasha Spider Venom samples. Then I will be able to determine the source of the evil fiend Kasha through this medium.
Of course your service in this matter will be rewarded...
