I hope you got enough rest, because this next task is a real doozy. I'm giving you the Dark Evil Thoughts so you can take them to the entrance of the East Branch of the Polar Royal Palace on the far shore mountain.
When you use them, the Thought Composite sealed under the Polar Royal Palace will slither out. You must exterminate it immediately! Don't take pity on it, even if it makes sad dragon eyes at you.
If we disperse the Thought Composite, it cannot be completely reborn. Without its presence, the conditions in the Ancient Polar Ruinss will gradually improve. We must win this battle!
