The Duct system is a transportation feature exclusive to Tales of Legendia.
On the World Map are glowing red platforms that can be activated, allowing access to the Duct system from that location. The Duct may then be used to quickly teleport from one location to another if the Duct has been activated in that location, while the Duct located near Werites Beacon allows transportation to any activated Ducts. During the story, Will Raynard explains the Duct system to Senel Coolidge as they leave Werites Beacon for the first time. It is later revealed that Ducts are a product of the ancient Terises civilization.
