Salva II

Salva II was a planet in the Salva system on the Federation-Cardassian border. It was home to a Federation colony until the system was ceeded to the Cardassian Union following the Federation-Cardassian Treaty in 2370. Rather than stay within the Demilitarized Zone, most of the colonists relocated to Marva IV. Afterwards, the planet was largely left unnoticed by the Cardassians and occasionally used as a base by the Maquis. 

Joshua Petrelli was brought to Salva II in 2378, where he was reunited with his mother aboard the USS Baldwin (NCC-2013). (: Mother and Child)
