The pack was formed in the year of 1903 when Eve triggered her werewolf curse, becoming the thrid in existance, and five years later Esther and Andy were turned too. Unlike the Shape-Shifter packs in La Push, they do not protect people from harm and have been on murder rampages for over a hundred years. Before Eve turned her mother and sister into hybrids, she would try and convert other Children of the Moon into shape-shifters like herself. First she would feed them her blood and kill them, when the Werewolves were awake they needed to complete their transition into vampire by drinking fresh human blood; something she had no clue about. 24 hours after, the hybrids would become unstable and rabid, then start to bleed out from their eyes. Sometimes Eve would kill them and other times they would just bleed out and die, in the end not one would survive. During a ten year span, she had wipped out a great amount of werewolves that all died in the transition, and it wasn't until Eve turned her family that she decided to test a theory. As Andy and Esther were transitioning, Eve gave them fresh human blood to feed from...and they completed the transition into vampire. By the time of 1987, Eve increased her pack's numbers up to 10 hybrids.
After Rising Dawn
During the time after Eve returned from the battle and near destruction of the Volturi, Eve and her Shape-Shifter pack traveled to Seattle, Washington to wipe out the Seattle Coven owned by the vampire Kristie. As the hybrids were going to destory the entire coven and mark it Werewolf territory, Nahuel's Coven had come to there to offer the Seattle Coven a chance to be allies; almost entering a battle against Eve's pack (a battle the volturi would have won). However at the last minute, the wolf pack decided to leave both of the covens alone when Eve had them travel East over to Portland, Oregon; a city that's literally crawling with werewolf pack. They spent over a month in Portland, enhancing Eve's pack members.
This pack of Eve Lydias (Alpha), Esther Lydias (Beta), Andy Lydias (third-in-command), and alittle over a month after Rising dawn,seven pack members.
