Denali coven

The Denali Coven is a vampire coven (though they prefer the term "family") comprising Kate, Garrett, Carmen, Eleazar and Tanya. The Denalis are among the few vegetarian vampires in the world, along with the Cullens. They are very close to the Cullens, being some of the Cullens' most loyal allies and considering themselves their extended family. The Denali Coven is located in Denali, Alaska so that its members can live alongside humans without too much trouble.

History
Originally, the coven consisted of Sasha and her "daughters", Tanya, Kate and Irina. At an unknown time, Sasha also secretly created an immortal child, Vasilii. When the Volturi found out, they came to destroy the entire group, but only killed Vasilii and Sasha, since the others knew nothing about him.

At some point, the vampires Carmen and Eleazar found the three sisters and joined them. Also at an unknown time, they met the Cullen family, and the two covens became strong allies and close friends. Tanya developed romantic feelings for Edward Cullen, but he did not reciprocate.

New Moon - Eclipse
A vampire named Laurent eventually came to stay with the Denalis. Laurent had recently left a coven of non-vegetarian vampires, and was ready for a change in his life, which happened when he and Irina fell in love. At one point, however, he returned to Forks as a favor to his old friend, Victoria, to 'get the lay of the land for her' so that she could hunt Bella Swan. While he is there, he runs into Bella in the middle of ;hunting. When he was about to attack her, a pack of shape-shifters, who the Cullens happened to have a treaty with, killed him before he could get to her. A little under a year later, the Cullens called for aid from the Denalis. Victoria was creating an army of newborns to destroy the Cullens and kill Bella. The Denalis agreed to help them, if they could avenge Laurent's death by wiping out the shape-shifter pack. Carlisle refused to allow this, and the Denalis abandoned their long-time friends. The Cullens were forced to form an alliance with the shape-shifters instead, and successfully killed Victoria and destroyed her army.

Breaking Dawn
The Denalis later felt terrible about abandoning the Cullens. Soon after the battle, the Denalis, except Irina, attended Bella and Edward's wedding. A half-year later, Irina decided to visit the Cullens and finally make peace with them about Laurent's death. When she arrived in Forks, however, she saw Bella hunting with her shape-shifter friend, Jacob Black, and what appeared to be an immortal child (Renesmee). Remembering Sasha's fate and her anger at the Cullens for not avenging Laurent's death, she went to the Volturi and reported the Cullens. The rest of the Denalis were once again called upon by the Cullens for aid. Renesmee, the child Irina had seen, was really Bella and Edward's hybrid daughter. The Denalis, after some persuasion, agreed to testify this for the Cullens against the Volturi.

When the Volturi arrived, Irina realized she had been wrong. After admitting this, Caius had her killed to try to provoke a fight. His efforts failed, and the Volturi departed after Aro decided Renesmee was not a threat. The remaining Denalis returned home after the confrontation. They were joined by the nomad Garrett, who was said to have joined the Denalis due to his romantic feelings for Kate.

Trivia
The Denali coven is known as the third largest vampire coven in the Twilight Saga.

They used to lure men to their death by seducing them and engaging in sex with them, before feeding on their wictim, but the on the long term the strain wore on them and the Denalis started to feed on animal blood. They, however, kept enjoying the company and nocturnal activities with men, both vampire and human, which by now could survive the experience. This may also be the origin of the succubus myth: a demon that assumes a woman's aspect seducing men to have sex with it.
