Not much is known about the Watcher other than the fact that it is the single most powerful ship that was under the command of the Koballah. Many stories of old tell of the Watcher and surprisingly, not all of them are evil. There are some writings that tell of the Koballahn Watcher riding to the rescue of other races.
There isn't much else that is known about The Watcher. Who built it and how it is powered is unknown. Most of Anarkand has accepted that the Koballahns have left their world on The Watcher never to return as neither the craft, nor any Koballahns have been seen on or around Anarkand for centuries.
