This is such a common question I'm sure it's already been asked, however, I can't find it, so... In "Trouble with Tribbles" was it ever explained who those Klingons were. In the DS-9 episode "Trials and Tribble-ations" when questioned by the Chief, Bashir and Odo, Warf tell them it is an issue that Klingons do not discuss with outsiders. Was it ever explained in any greater detail, even the a book??
