Cookie Dough arrived in Appalachia a year after The Great War. She was on her own and had to learn the ways of the wasteland. Over time she met other wastelanders like herself and made a group of friends. On the surface she's a bit of a tough cookie and can handle whatever the wasteland throws at her but deep inside she's really a big softie. This is where she gets her name, Cookie Dough. She is soft and sweet but if you apply too much heat she can get hard.
Cookie Dough loves helping other wastelanders beacuse she hasn't forgotten how clueless she was when she first entered Appaclachia. So she spends a great amount of her time building houses, stores, warehouses, etc. for the less fortunate around her.
Over her time in the wasteland she's explored various historical sites which have inspired her to get more into investigating, learning, documenting, and even re-building history. So when she's not building for others you may come across some historical construction conspicuously placed in the ruins of West Virginia, built by none other than the magnanimous Cookie Dough.
