Fast answer: In Drums of Autumn Chapter 32, Roger reads Geillis Duncan’s grimoire and learns more about the stones, dates, gemstones, and failed travelers. The book is part occult manifesto, part field report, and part giant warning sign Roger absolutely does not have the luxury of ignoring.
Thesis: Chapter 32 works because it makes the magic feel procedural without making it safe.
Lightning-Fast Recap
Fiona gives Roger access to Gillian/Geillis’s writings. Roger reads through theories, observations, and records of people who tried to pass through the stones and did not survive.
The information is useful, but it is also horrifying. Dates matter. Stones matter. Preparation matters. And even then, there are no guarantees. Time travel in this universe remains less DeLorean, more industrial blender with vibes.
What This Chaptah Is Really Doing
The grimoire is a craft cheat code. It answers just enough rules questions to make the next move possible while adding enough danger to keep the story from feeling easy.
Geillis’s voice also matters. Even in notes, she is drunk on power, theory, and destiny. Her obsession reframes Roger’s journey: he is using knowledge gathered by someone morally radioactive. Good information, terrible source. Welcome to the internet, but with human sacrifice.
Why It Matters
Chapter 32 gives Roger the tools he needs to attempt the impossible. It also makes clear that love is not enough to survive the stones. Knowledge may help. Arrogance may kill you. Fun little travel advisory.
