Also, keep in mind that none of the dangers in the book are really “complete.” They’re collections of ideas and prompts to get you started. So if you see an element you really like, you can totally mix and match or repurpose it.
Psychonaut invaders make great hunters for the space madness danger, for example. They can be just like an alien invasion. In your game, you’d just have to make sure they’re not really aliens. Maybe hallucinatory mirror-world Moonicorn is a totalitarian fascist and the transport guild is powerless to stop him from accessing reality through their stargate bodies, but they’d rather just cover it up than actually address the problem, especiall because the oneirofascisti have promised to maintain their monopoly.
