This interlude answers the immediate question of why they were in stasis for 2500 years instead of the planned 100 years.
Perhaps when Jamie programed the machine, he programed it to cover other sections to keep Loka and his ilk out. We may not know the answer until Book 3. Remember, Jamie gives us information that sometimes appears in a future chapter.
Before we can find that out tho, we still need to get thru Part 3, The Circle of Ondra, as we still have Loran to deal with.
I'm guessing that Book 3 will then begin to deal with Hippolito and Gude.
