Oh My Goods!
Do you play Longsdale in Revolt before Escape to Canyon Brook, and are Canyon Brook cards used during Longsdale?
Yes, play Longsdale first. Ignore Canyon Brook cards and rules until Longsdale is finished; the Longsdale cards are then shuffled into the main deck and Canyon Brook cards are added as you play its chapters. Buildings, characters and assistants numbered 50 to 60 are Longsdale and 61 and up are Canyon Brook.
