Afton

Afton is a vampire and a member of the Volturi guard. He is listed in the index in the back of Breaking Dawn, and has the gift to make himself invisible to his attackers. His mate, Chelsea, showing a more valued gift, is the only justification for his presence in the guard.

Breaking Dawn
In Breaking Dawn when the vampire Irina reports to the Volturi about the creation of an immortal child in the Cullen family, the entire coven is ordered to travel to Forks to punish the family for such crime. It is therefore assumed that Afton is present.

Mental invisibility
Afton's gift is to make himself mentally invisible to his pursuers. Someone who hides behind him will also be invisible. However, his power is much more limited than most of the other Volturi guard's gifts; it cannot protect from the user, also a person with enough focus can easily see through his "shield". Which is why he is not considered a guard or a member worthy a place within the Volturi.

Since this power works on a mental basis, it can be rendered impotent by Bella Swan's mental shield.

Chelsea
Chelsea is Afton's mate, recruited by Aro a long time ago as a means to bind other vampires to the Volturi. Chelsea's powerful gift makes her a prominent member of the coven, which is why she is kept around. She enjoys using this position to get what she wants, and Afton is kept within the Volturi for this reason.
