Well, I don't particularly remember any lores or backgrounds of NPCs, but pretty much most of the information about them are from the LN or WNs. You can even get their background information in their wikia page itself too.

If you are talking about extra stories outside of the novels translated or not, then I can give you some.

The treant ZytQae.

The pleiades having their meeting.

or even a bonus chapter of a messenger death knight's story said by the other commenters that is coming out soon.
