Defeat abyss akbas and cruel akbas in Ashwood Trench to acquire akba's manes. Then, go to Ashwood Post and talk to Chris Wincott. Use your quest tracker to see your progress.
Chris Wincott: Wow, I've only heard about it, but it's so nice. NakanoAzusa: What is? Chris Wincott: Akba's manes you brought for me, they're really soft. HiiragiKagami: Really. I feel happy when I feel it. Chris Wincott: This will be money. I can tell already. Guaranteed! NakanoAzusa: But it's hard to find, how could you sell it? Chris Wincott: What are you talking about, if it's good enough, the Chris Wincott: nobles of this country would pay anything to buy. Chris Wincott: It's extravagant, but who cares? NakanoAzusa: I don't understand since I'm only a poor Aitan. Chris Wincott: We should aim at rare products. I need more of these! Chris Wincott: Could you help again? HiiragiKagami: You'll become rich soon, pay us enough, then we help! NakanoAzusa: I told you not to make decisions on things like this.
