Principle and Method

There's a problem. According to this Structural Map, we need five Vargas' Spears to keep the Milieu from working. Vargas was an ancient official in charge of the Milieu's beginning and end. He kept total control of those spears, so he was the only one who could control the Milieu. I've known the location of the spears a long time, but I never knew their value. They've been kept in the Harpies' Treasure House. Have you heard about it? It's been underground a long time and the Harpies keep the key. So, your goal is clear. Destroy the Harpies at the Red Stone Road and bring back the Treasure House Key.

Without the key, the Treasure House won't open. I know the location of the treasure house, so you can go get the key right away. Destroy the Harpies at the Red Stone Road and bring back the Treasure House Key.

Right! You brought it! I was so anxious, waiting for you. I'll go to the Treasure House. You wait here. Thank you.
