E'Bar was the home of the Taredhel after they returned to Midkemia. It was supposedly built near the rift between Kelewan and Midkemia. It was a city of magical shaped stones and rocks that the Taredhel galasmancers had formed with their magic.
E'Bar was invaded by Dread when some of the leaders of the Taredhel opened a rift into the Void. To prevent the Dread from overrunning and consuming Midkemia, some of the Taredhel magicians erected a ruby dome around E'Bar to hold the Dread in place. The dome and the city were destroyed when Pug sealed the rift by using an immensely powerful spell to crush E'Bar with the mountains surrounding it.
