Hey guys, I have started to get into Star Trek, and am currently almost done with the first season of the original series. I’m watching the first episode that contains the klingons in it, however I have seen bits and pieces from the next generation and know that Worf is a Klingon. I’m aware that the next generation takes place about a century after the original series, but if the federation is at war with the Klingons, how is worf seeving on the enterprise?
