The Klingon Culture page has a list of bladed weapons, ceremonies and a list of the Great Houses in the High Council in 2293, 2294, 2310 and 2312. Question: What happens with the average Klingon, of a minor House no one has heard of, with no lands, no combat who works say in a foundry? Or a shop? Maybe makes the B'rel door mechanism?
Watch out for new story material and character development.
The Excelsior page gets dusted off with new material from the ST: Excelsior Writer's Guide (2001) and material from the never-written ST: Excelsior TV series of the late 1990s from non-existent scripts.
