Ok, there were 2,538 objects, but 2,000 were "lost." Meaning not destroyed. Meaning still exist.
However, the world is destroyed if the remaining 538 objects are brought together.
Why does the "destroy the world" condition change whenever we're uncertain of the precise location of one of those objects? Shouldn't they crave to be reunited with all of the other objects, not just the ones that humans currently know the location of.
If someone who knows the series better than me could explain, it would be appreciated.
