Eileen grew up in "middle of nowhere," Vermont, younger child of two. She had a very Rockwell childhood, as she describes it - nothing really stood out in her small town. Her parents were a loving couple, she argued with, fought with, played with and loved her brother Michael. She made friends, skinned her knee, dared and was dared to go into the abandoned "haunted" house down the road.
She loved seeing the leaves change in fall, loved playing in the snow until she was sick of it, then loved everything turning green and starting to bloom in the Spring.
There was nothing in her life that suggested she'd do anything more than have a happy childhood, graduate, go to school and give her folks grandkids while working on her career. Nothing, really, except her brother.
Helping her brother
Michael, her brother, was one of those types who couldn't stop tinkering. Learned everything. Graduated early from high school with a patent for a new battery design that was going to have a huge impact, both on life and his personal economy. Little Sister was always there, though, willing to help (or try to, at least.) While not the genius Michael was, she still had a good grasp on the tech, and on testing. Plus she turned out to have a good head for budgeting and economics - as well as pushing him to patent his designs.
Michael went on a world spanning vacation after he graduated, wanting to get out and see everything with the money his inventions were already garnering him. College was the plan - that and trying to be a hero. Eileen, in the meantime, finished school - she wouldn't have to worry about paying for college, thanks to Mike, but wanted to stay close.
Eileen's behaviour started to change after a short time in Paragon.
There was a solution, though. It was a long shot - a gamble.
The peaceful life on Meia that she'd finally decided to embrace was shattered one day.
Loss and turning point
Eileen's now back in Paragon. She's still waiting for some word about her brother, though by now he's presumed lost somewhere in Praetoria.
She continues developments on the Cryosphere suit, both for her own use and to once again present it to fire departments, starting with the PCFD, for use in fire fighting. She continues to fight, as well - and will often be seen lending a hand when the Hellions have gotten a bit too rowdy.
She will sometimes lapse into Ji'ann pidgin, mostly to swear at whatever she's fighting.
