House of Mo'Kai

The House of Mo'Kai was a Klingon Great House from a 24th century Holographic program.

After taking over the USS Voyager in 2374, the Hirogen put the Voyager crew into battle simulations on the ship's holodeck. Kathryn Janeway was disguised as a Klingon who claimed to be from the House of Mo'Kai as she unsuccessfully faced down Karr.
