I always thought that the Klingons in Star Trek owed a debt to the Vikings.
Blasphemy! A Klingon attributes his or her warrior like ways to Kahless. Actually, I don't remember if that is true now.
I used to speak some Klingon and could read and write a lot of it. It's been too long or I'd quote something about Kahless from the Klingon proverbs book which I can't remember the name of. I have it upstairs.
I'm not really a Trekkie but I used to enjoy learning the Klingon language and ways. It's a long story and I have no idea where it would fit in the list of topics, perhaps in Miscellaneous. I really need my books to refresh my memory.
tlhIngan maH! -- We are Klingon!
