TAHOMAZ: What are you thinking?
YUWEN: After we rescue Pnimm, we should be able to plot a course to any point in the Omphalos' history. This will allow us to leave a recording device, which we can pick up much later to check whether Ajact was present at any intervening point.
TAHOMAZ: Uh... and you can make a "recording device" that would do that? There aren't any angels in the Furthest Ring.
YUWEN: I can make anything.
TAHOMAZ: Okay.
TAHOMAZ: Either way, we have to rescue Pnimm first.
