Do we have any information on whether Onyx, Shield World, and the Ark are Fortress Worlds? --68.44.13.236 16:37, 12 September 2007 (UTC)
The Seven Halo rings are the Fortress worlds, not the Shield World, Onyx which in its own right isn't even a world and the Ark, which is a location on Earth. --Ajax 013 16:54, 12 September 2007 (UTC)
