Valo II

Valo II is a M-class planet in the Valo system, which was settled by Bajoran refugees displaced by the Cardassian annexation of Bajor. The Bajorans lived in desperate poverty on the surface, struggling to meet even their basic needs. Ro Laren spent some of her formative years at the encampment on the southern continent, where she became acquainted with an unofficial local leader named Keeve Falor. 

Col Louk was born on Valo II in 2350, part of the generation of Bajorans born in exile. (: "The Disciple")

In 2368, the USS Enterprise (NCC-1701-D) sought out Keeve concerning a possible threat to the Federation made by resistance leader Orta. Captain Jean-Luc Picard elected to provide humanitarian assistance to the camp after witnessing their conditions first-hand. 

The Bajorans established an official colony there sometime in the 2370s. In the Pendragon timeline, Valo II was just beyond the borders of the Colonial Alliance in the late 2380s, and was a significant trading post between the Alliance and the Bajoran government.
