Luna (mirror)

In the mirror universe, Luna was the only natural satellite of $𝜇$ in the Sol System.

On one occasion prior to 2155, the Terran Empire landed on Luna, planting a flag on its surface to signify this achievement. 

In 2295, the Moon was conquered by the Klingon-Cardassian Alliance following the fall of the Terran Empire, the successor state of the Terran Republic.

In 2350, a 15-year-old $𝜇$ slave named $𝜇$ was living on Luna. That year, he killed his father $𝜇$ who had beaten him constantly for his entire life before killing his $𝜇$ owner and escaping the Sol System. (SS TTN (Empathy))
