House of K'toh-maag
The House of K'toh-maag was the Klingon house Captain Kathryn Janeway claimed to belong to while bluffing the characters of a Hirogen's Klingon simulation in 2374. 

Neelix, brainwashed into believing he was one of the Klingons in the program, claimed to have never heard of the house. Janeway responded that she was not surprised, as the house was from far away from the setting of the program. ()
