"You should, there's some rather interesting things in those books. For instance, I was particularly intrigued about an experiment which discovered that fuels from the remains of living things in the past, while far less efficient than Dust, does not lose its energy when exiting Remnant's atmosphere." As she said this, she looked around the room. "Quite interesting. They've constructed a small mirror system that allows sunlight in from outside. Now, I wonder what these do..." In front of them were five devices with a spherical button. Pushing one, the objects rotated around the room as the center crystal opened to show a mirror. "Hmmm..." Pushing another button, the devices swiveled again, focusing thin beams on the center crystal, which closed. She tried the other buttons which produced similar results except for the last button, which reset the entire device. "I see, so you were correct about the refraction part. The goal of this... dungeon mini-game is to create a light refraction pattern that is projected to the center. However, when you manage to focus the light to the center, the mirror closes. So one has to figure out the combination to focus the refracted light to the center while keeping the mirror open. Would you like to give it a shot, or do you want to just do it the, ah, manual way?"
