Zagros VII was a ringed world, shrouded in bands of thick green hues cloud layers.
In late 2259 it was the site of a Ranger training camp, established with the assistance of Anla'shok Marcus Cole. Its existence had become known to the Shadows and soon Morden would have Lord Refa arrange a blockade of the planet to keep them there so they could destroy them. Less than a week later the colony was surrounded by Centauri blockade mines. After two weeks, Cole would escape the blockade in a Sky Serpent launched from a Sun-Hawk piloted by Drosak, who is killed in the attempt. After making it to Babylon 5, Cole returned with Sheridan and Delenn aboard the newly completed White Star 1 and managed to clear the blockade, allowing the other Rangers to escape just before a Shadow Vessel arrived to finish them off.
