Karazek

In the mirror universe, Karazek was a planet of the $𝜇$.

In 2378, following a provocative attack on $𝜇$ by the Gorn, the $𝜇$ launched an invasion of the Hegemony. Within five weeks, the $𝜇$s conquered Karazek, $𝜇$ and Ozannot. The invasion was halted when the Terran Rebellion destroyed the Klingon SoHcha Fleet Yards and liberated $𝜇$.
