A Teleporter is a type of Adept magic. It involves a person a person teleporting to another place. They can go anywhere as long as that have been there before. In Dark Days, Fletcher stated that it is hard to teleport into a moving target thats moving fast, such as a car. A teleporter, along with the Isthmus Anchor, can open up the portal for the Faceless Ones to return.
Deaths of the Teleporters
A man named Batu has gone around killing all but one of the teleporters in The Faceless Ones. In the book, it says that Batu killed another teleporter fifty years ago, and gave it to the Sea Hag. Currently only Fletcher is alive. This is because he needed him to open up a portal for the Faceless Ones.
