I don't know if this works as an entire outline (I mean, I've left off the context etc, this is very much the bullet points) for Act One of Tourist's Guide but it's a better bare bones than I had:
Opportunity, distracted while waiting for Charity, sees Edmund walk through a wall having made off with a crate of beer he "won" at a pub quiz and basically stiffing the rest of the team, dismissed it as seeing things until she saw what happened with Charity - from a distance.
Opportunity literally sees Ezekiel lead her sister into a painting.
O pursues Ed, having realised he is probably able if not willing to help.
Ed accidentally Moves Alec while trying to both pursue B and escape O (Alec’s presence is not coincidental but he doesn’t know that yet).
How does Opportunity persuade him to help her? I’m betting money is involved.
B becomes object of pursuit from Ed with O in tow
B is found and intractable/difficult, they are dragged into King Jack's London
B sets Ed to find King Jack, Ed refuses, Bodge is revelatory about him until he co-operates
King Jack is found, by Opportunity rather than Ed. The Stage, the explanation of the Mask
Use of the Mask (Alec's idea) to make Bodge stop being slippery about what she's done and what's happening
Movement into a different (London At War With Country) to try to work out what the fuck has caused what Ed and Bodge have notice of the Collapse, or rather Who, by talking to other Born Movers. Conflict. Potential actual fighting, etc.
Opportunity reminds them that her sister has been pulled into this reality and doesn't know the rules, by someone else. She describes Ezekiel
Manon & Mr. Sands are Not Speaking over whose fault it was that Ezekiel was able to access (Masonic?) texts - and that non-Movers/loci had that information, but are both pissed at Bodge (as are all the Born Movers) for appointing Ed - this information is extracted from some nominated underling of Mr. Sands using an improvised Mask - Ed's idea, Opportunity is very uneasy with Masking.
Which is how they find out about Katherine; Katherine, Ed says, is the kind of person (he's seen her at work?!) who never leaves her phone off even when she's been told to ten times.
The Collapse becomes noticeable…
Unfortunately I think it also takes up a lot of the ground I was planning on using for Act Two, and has conflated them. Once again, lack of material is a serious problem. I know what Act Three ENDS with. I have a vague idea of how to get there. I GUESS Act ONE can end with a death, which immediately instills a sense of urgency, and I have a reasonable idea of whose.
I'm struggling with PoV stuff a bit. My instinct is always multiPoV but I think that kind of didn't work in Soft Inheritance?
