Tor Zireael, the Tower of the Swallow in Elder Speech, is a place about which few people except the Aen Elle are aware. It is a tower containing many magic portals through which one can travel to many different worlds. It is considered a legend by all but a handful of people; those who have actually seen it. These people include Ciri, Vysogota, Vilgefortz, Geoffrey Monck and Buyvid Backhuysen. It lies on the north shore of Tarn Mira, a trefoil-shaped lake, one of the many in the Mil Tracta region.
