Alternatively, with the whole 'history must be changed [sic?]' note, the Calling could be sort of like a metaphysical emergency evacuation, plucking each of them out of the Source in advance of a known event horizon. I've interpreted the state of having been Called very tentatively and loosely as being like 'going todash' in the Dark Tower books--the person is still sort of in their homeworld, but they've glitched over to existence in a different one that overlaps it.
