And to be honest, Zev could feel that the kid was indeed the next host after the Godfather, not a system host several generations after the Godfather.
However, whether she came from a decade in the future or way further...
It was still vague.
[If we can check her bloodline and compare it to the people in our era now, maybe we can guess which era she came from.]
The baby said she was a halfling of the blood clan, but she spoke about it so casually, without any intention to hide it.
Nowadays, the blood clan is still in hiding, and anyone related to the blood clan will more or less try to hide it, afraid that the celestials will bother them.
Since the kid could be so open about her identity, it means the blood clan in her era had already come out of their hiding place, and possibly, they had already established a certain influence until the celestials couldn't easily disturb them.
