Sheva II was the second planet of its star system. This system was in Cardassian territory.
The site of a Jem'Hadar breeding facility, Sheva II was one of the targets of General Martok's "cavalry raid" in 2375. (DS9: "Once More Unto the Breach")
This planet was only mentioned in dialogue.
This planet's quadrant of origin is inferred based on the position of the Cardassian Union as seen in the star chart appearing in the Star Trek: Picard episode "Maps and Legends". According to Star Trek: Star Charts (p. 47) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), the primary of the Sheva system was a M-class star.
According to the script, the pronunciation for Sheva was "SHE-vuh". [1]
