From Septin's implied words, we know that we can find the scroll we want in a place called Altande. Then there is the tomb adventure, full of robots and snow elves.
Here, you have to flip the switch opposite the door to turn it on. This dwarf centurion is very powerful, which is totally different from ordinary robots, especially his steam attack. If the level is low, we can't discuss it. After fighting with the centurion, he entered a purposeful room. There were two people quarreling in the room, and then they started fighting. If they find you at this time, they will attack together. We might as well hide first, and then pick up a cheap switch to open the iron gate in front when they are finished. The destination is close at hand!
Finally, I came to the room where the scrolls were put. There is a set of buttons in the room. We should first put the square dictionary from Septin's Hinting at the Old Man in a marked place, then press the second button four times, the third button twice, and count the fourth button from the right, and the scroll will appear.
