In The Strange RPG, you can change your focus whenever you translate. One thing that isn't clear to me is if you always should use the same focus on repeat visits to a given recursion. For example, if you travel to Ardeyn, can you have Abides in Stone the first time you visit, and then Works Miracles another time?
If you can choose, suppose you return to your native recursion (or earth). Can you have a different focus then? That seems weird. It means that people may change professions or even species when you see them on different occasions.
Related: I am already aware that, if you have a draggable focus, you can choose to drag it, or not, on each trip (if I'm reading the book correctly). So there is some president for changing your focii on different visits, but again, some odd things can happen if you extend this too far.
