Oh! My apologies on the delay in responding here, we're winding down summer. The "genre appropriate" part is intended to be repeated at each benchmark (30, 40, etc) with a new event each time; it's the "build up" and "plot thickening" part of the game, where your character demonstrates who they are. Think the part of a detective novel where the detective is (one) interrogating a witness and finds a flyer for a bar, then (two) goes to that bar to find a clue that points to their client, then (three) confronts the client at the manor but they're (gasp) dead. Each is very much an event that is genre appropriate/tropey, but the order is open for you to tailor to your genre and your story, based on what's already happened.
Thanks so much for clarifying! I thought that was the case, but I found myself accumulating Peril so fast that I wondered if the intent was to move at a quicker pace. Several of those midgame "beats" building one after the other feels right for this story.
(PS: I've been doing an actual play with Calypso here for anyone who's curious how that pacing can look in play!)
