Siobhan

Siobhan (pronounced "Shih - von") is a vampire who is the leader of the Irish Coven. The other two members of her coven are her mate, Liam, and a female named Maggie. She is friends with Carlisle Cullen and came to help his family testify against the Volturi in Breaking Dawn. She and her coven are not "vegetarians", but her coven is shown to be very civilized.

Vampire talents
Like a regular vampire, she possesses incredible speed, strength, immortality, marble skin and beauty.

Outcome Manipulation
Siobhan does not think she has a gift, but Carlisle believes that she can influence events by willing her desired outcome to play-out in reality, but it requires her full concentration. Right before the Volturi arrives to terminate the Cullens, she wishes for a good outcome of the situation, which works out exactly the way she wants, although the vampire Irina is sacrificed in the process. Afterward, she begins to believe that she does indeed have the gift.

Physical description
Siobhan is described as having a huge body that moved in smooth undulations and was both beautiful and mesmerizing to watch.
