I am ashamed to admit a deficit in my trekknowledge,though, in this case, there isn't much to know, canon-wise, I think, but, to any of you 'Specialists'(Get the Final Reflection re there?) in things Klingon, was there not a DS9 or other novel,that dealt with these aliens who once conquered Qo'nos long ago? If so, I'm curious to find out what this entailed. P.S....I'll put in a good word with Kahless for ya if ya can!
