There did not seem to be any flaws in Adrian's logic. First of all, the oil lamps were indeed an indication of the galaxy. Secondly, it was impossible for the answer to the puzzle to be to line them up in a straight line since literally anyone could figure that out. Moreover, the people of the past loved to twist and turn their answers.

Hence, Adrian believed that the key to activating the mechanism was by rearranging the Big Dipper. In other words, he needed to locate where the Big Dipper should be pointing and shift the oil lamps accordingly.

Rozi silently acknowledged Adrian's deduction. After observing her surroundings, she said, "Here comes the million-dollar question. We've lost our sense of direction, so which way is True North? We won't know how to rearrange the oil lamps if we can't identify this."

She had brought up a very important question, one that stumped everyone. There were no ventilations within the palace, and everywhere without oil lamps was shrouded in darkness.
