Puzzle
Library planetarium puzzle
Three orreries, three clues
IGN's planetarium page splits the puzzle into a man, a woman, and a skull. The man uses the Star Chart in the Astronomer's Office, and you step only the lower four lights. The woman uses the Organic Astrology clue in the Drawing Room, the lines through the head and the hands, and you step the four lights those lines indicate. The skull uses the Blood Poem on the Natural Philosophy Shelves plus four constellation points on the lounge window, stepped from right to left.
A correct orrery reveals a larger bouncing orb. The same cabinet is the start of the Durandal route: in the Curiosity Cabinet you light four orbs, then Aerial Rush across them into Lisa's Laboratory.
What a diagram would add
The sources say 'lower four' and 'right to left' without a labeled ring. I am not assigning clock positions I cannot see. If a light refuses to lock, re-read the clue item rather than a guessed diagram.
What I ran into
I wanted to number the orbs 1 through 8. The article never does. Stopping at 'lower four' and 'right to left' felt incomplete and was still more honest than a diagram I would have to apologize for.
Questions
Where is the planetarium?
In the Library. The man, woman, and skull each have a clue in a nearby room.
Does this unlock Durandal?
The Curiosity Cabinet's four orbs are the approach to Lisa's Laboratory, and that chest is Durandal. You need Aerial Rush first.
