It should be possible to right-click characters to reveal their second role; in this case, if you right-click Deva (the angel), Draco should appear. If that doesn’t work, something went seriously wrong :D
And yeah, when we brainstormed ideas, I also quickly thought about having a dynamic play depending on the characters available, but quickly discarded it as way too much scope. Maybe with generative AI tools, something like that would be possible.
