How do different flows of time interact?
In a moment of improvisation, I created an extremely dangerous orb that is frozen in time by a spell. The next session will be in a couple of weeks because of Easter, and I realized that stopping time in a small space would have weird consequences. For example, what would happen if something were to go through the field separating the two times? And how do forces work on the time-bubble?
A more general form of my question is, how should I handle spaces with different flows of time, and how would they interact?
