Monster's nest ruin

Hm… it seems that he is right. No matter how much I check it, the residence of Black Hawkarrows that you caught and the place I discovered resemble each other closely. Does that mean it's the grave of the monsters? I don't really want to touch it anymore. But, it doesn't feel right to just leave it; I need something appropriate to block it… That's right! There was that. You have some time right now, right? Please bring back Old Board from Boundary of Life. I have seen a board there for sure so it shouldn't be hard to find it. I think that I should block off the grave with that board so please hurry.

Please bring back Old Board from Boundary of Life.

You brought it. Then, you can leave now. Thank you so much for helping today. I should go finish this business. See you later.
