The problem with librarians is that over time they inevitably become indistinguishable from angels
Given all the extra eyes (for reading) and all the knowing of forbidden things (from reading)
This is alright, if a bit unsettling, the real trouble comes when some careless god or other scoops them up thinking that they had fallen out of the nest
Which means that most librarians are only good for 2-3 millennia of work, barely enough time to train them, before you have to get a new one
