Volan II

From Memory Alpha, the free Star Trek reference.

Volan II is the second planet in the Volan system on the Cardassian side of the Demilitarized Zone, and is the location of a Federation colony. William Samuels, the Federation colonist who confessed to the 2370 bombing of the Bok'Nor (possibly under duress) while in Cardassian captivity, lived as a farmer on Volan II for nearly twenty years.
