A Na’fhuil or halfblood, who unlike the more common Jumpers of the race travel inside the Rip instead of pushing off its boundaries. Walking into the Rip is crippling, the extreme pain and oppressive atmosphere debilitating. A Walker can make small changes that affect reality in the human world while within the Fae passage, long minutes spent inside the void passing in less than a second outside it. Na’fhuil magic is often confused with the ability to manipulate time. Abigail MacCarthy is the only known living Walker.
