House of Mo'Kai

From Memory Alpha, the free Star Trek reference

The House of Mo'Kai was a Great House in the Klingon Empire.

In a holoprogram created by the Hirogen in 2374, the Klingon character of Kathryn Janeway was from the House of Mo'Kai and claimed the House would never yield while fighting the Alpha Hirogen. (VOY: "The Killing Game")

It is unknown if the House of Mo'Kai existed in reality.
