Long way to fall

There are many answers to the question as to what it is that lies between heaven and hell. Physically, one can answer that it is the planet we exist on, Earth. Another is that the answer is limbo, that state between the ultimate high and the ultimate low. But all are populated by Angels. Those that keep the pure high ground and those that have descended as low as they can go. In between we have those who are on their way down. Or are they on their way back up?
