Here is Isabella, meeting with Linus, who has flown in to make sure that Bethel is running fine. She has a lot of reports - all carefully maintained since the beginning of her time as host leader - to go over with him.
"Eleison had much more advanced technology than is currently present on the ground in Samaria. It is likely that non-Samarian human civilizations have developed beyond that technological point in the intervening centuries, although your ancestors assigned significant probability to their rendering themselves extinct through war. As of the time of the archangel Gabriel Aaron, there were still other human societies in the galaxy, but I have no more recent information."
"She says there are some humans left," says Alleluia, "but the ones who are still alive appear to be mostly societies like ours at least to the extent of relinquishing their weapons, even if they kept more technology than we have, and that if they were still fighting she would have prioritized intervening there over a slow start here."
Alleluia looks at the books available, then shakes her head at them and starts poking around on the computers until she finds an e-book of reasonable starting grade. The alphabet, at least, is roughly the same, even if the precise ways the letters are shaped has degraded over centuries of handwriting and no typing. She begins to go over the simpler words with Ariel.
