Velos VII was the formerly inhabited seventh planet in its star system.

In or before 2357, a Cardassian internment camp was established on this planet. Bajoran Resistance members Surmak Ren and Dekon Elig, mastermind of the aphasia virus, were imprisoned there. Dekon Elig was killed attempting to escape the camp on stardate 39355.5. The internment camp was closed on stardate 46302. (DS9: "Babel")

This planet's quadrant of origin is inferred based on the position of the Cardassian Union in the star chart appearing in the Star Trek: Picard episode "Maps and Legends".
According to Star Trek: Star Charts (p. 46) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), the Velos system was a binary system with a K-class star and a F-class star. According to a map of the Cardassian Union – prepared by an anonymous astrography clerk, from the Cardassian Central Archives, in 2364 – Velos was identified as a Cardassian system.
