Technological/societal levels in your conlangs/concultures

For those of you that have concultures to go along with your languages,
what is the relative level of technology/social advancement in your
conculture? Try and give a year, at least within a half-century, that is
equivalent to a time line of European history.

And another, slightly related question. I'm contemplating ideas for my
"holy book". What kinds of holy books have you folks written or alluded
to in your cultures?
