Same as darkness can be more than just absence of light, nonexistence can be more than just "absence of presence". Somebody can be missing so hard that they are not only "not there" -- there appears a haunting non-presence, a hole in space that takes their shape.
Maybe, this is what the Knight is to Dess. Maybe, this is what the goners are.
There can also be the opposite of this. Some entity “lighter than light", more real than reality itself. It's us, the Player.
Since the balance needs to be kept, can it be that for us to be summoned, somebody had to be gone?
