Praxis Explosion

Canon History

The definitive history of the on-screen Star Trek universe: Memory Alpha.

Praxis was a natural moon of the Klingon homeworld, Qo'noS. It was the only moon of that planet and was inhabited. Praxis was used as the Klingon Empire's key energy-production facility in the 23rd century.

In 2293, Praxis was destroyed in a large explosion caused by over-mining and insufficient safety precautions. The explosion caused a powerful subspace shock wave and deadly pollution of Qo'noS' ozone, threatening the depletion of the oxygen in that planet's atmosphere within approximately fifty Earth years.

Praxis' destruction resulted in significant political change, as the Empire had to divert resources from their vast military budget to address the environmental change. Chancellor Gorkon realized that they could not afford hostilities with the United Federation of Planets and approached the Federation with an overture of peace. This set into motion a series of events, eventually resulting in a lasting peace between the Federation and the Empire through the Khitomer Accords.
