Renesmee Cullen

Renesmee Cullen is a supportive character in the final book in the Valinorian Chronicles (Second Incarnation; Return of Darkness). She was a female dhampir from Earth who came in contact with Valinor when Sandra, Lilith, Sonya and Jennie arrived to help solve a conflict between Renesmee's family (the Cullens) and the reigning vampire-clan the Volturi. This conflict was caused by Renesmee's birth.

Spoilers

 * Renesmee will initially be called Nessie, but after Lilith thinks it sounds too much like the Loch Ness Monster (whom she seems to have had contact with) the Queens decide to call her by her full name
 * Renesmee's birth-year was changed from the one in the original fandom to match the timeline in the Valinorian Chronicles
