Cairan found out about the Garou when she was five years old. She knew that sometimes her family left during the night while she slept, she had heard howls echoing through the night while laying in bed, but had followed her mother's explicite instructions to never look outside. She was curious though, and stayed up one night when she noticed her mother and father whispering and was sternly reminded not to look out the window of their ranch house...that's the night she saw her beloved uncle change.
Cairan asked her mom about it and threw herself into helping the Garou as much as she could after that. She took karate, as well as the dance lessons her mother insisted on, and studied hard in school. Her parents took her camping and made sure that she knew how to survive with just a knife. She intended on enlisting in the armed forces, but before she did, she fell in love and mated a Garou.
Within two years, she had twins. Over the next few years, her pack infiltrated a paper factory near them and vandalized it repeatedly, each time causing heavy damage, and at the same time gathering information. About four years after the start, they started fighting back. A practical army, armed with silver bullets for their guns, attacked the main places where the pack lived. The Garou and most of the kin went to the rescue...but they knew when they left that they were outnumbered. Others took the children, in twos and threes and scattered, to fight another day and avenge their loved ones.
Ciaran went east and stayed in the woods near a city in a cave with her children until she can find a job and a place to live. There was no peace there, so they left, to travel again.
Cairan found out she was kinfolk and what that meant when she was five...she's had a long time to know her role and be comfortable in it. She's worked as a bartendar, a waitress, a secretary, and when she was still in high school, in the forest service.
She tends to be reserved, but friendly and open, giving the impression that you can tell her anything but she knows more than she's telling.
