Ghosty hunter
From Tardis Wiki, the free Doctor Who reference
The term "ghosty hunter" referred to a group of people who hunted Ghosties in the late 21st century. By the year 2069, prejudice against Ghosties was common and they were frequently hunted for being aliens. Freda, who was half Ghosty once had her home set ablaze by these people, and she escaped by being sent through the Cardiff Rift to 2009 by Torchwood. (AUDIO: Asylum)
