Snow White has always been a tougher customer than her name implied. She tricked her husband Prince Charming into teaching her how to fence in order to exact revenge on the seven dwarves who had imprisoned her. Sadly, her marriage to Charming was short lived as she discovered his infidelity with her sister Rose Red. What happened to Snow in the intervening years between her divorce and the invasion of the Adversary is unknown. It is known that after the Adversary invaded at she was sent as an emissary to the land of Arabian Fables to enlist their aid. Sadly, she was unsuccessful. As things became worse for the European Fables Snow and Rose found themselves traveling together. Taking refuge in an abandoned house, they discovered a living skeleton in the oven. As the skeleton slowly retook shape it told its story, revealing itself to be Frau Totenkinder, the bad witch of many legends. Snow was immediately distrustful and disdainful, but Rose continued to treat the old woman kindly.
Somehow, Snow and Rose were separated from the Totenkinder and ended up being captured. The chain gang they were part of encountered the Bigby Wolf, the Big Bad Wolf. He freed them and led them to one of the gates to the Mundane world. Years later, Snow along with Feathertop the scarecrow was sent to find Bigby to convince him to join the rest of the European Fables in moving to the New World to create a town of Fables far away from prying Mudane eyes. Because he was attracted to Snow, Bigby agreed and let himself be cut with a lycanthropy stained knife so that he could shapeshift into human form.
After settling in Fable Town outside New Amsterdam, Snow worked in the Fable government, working her way up to Deputy Mayor under King Cole as the city of New York grew up around them. (Indeed, as the series begins Snow is the go-to-gal, while Cole is more of a beloved figurehead.) While investigating Rose Red’s supposed murder, Bigby confessed his feeling for Snow, but she rebuffed him. After Rose Red had been revealed alive and sentenced with community service in the secluded community of non-human fables called “The Farm”, Snow and Rose reconcile while Snow tapped reserves of bravery and ingenuity in fighting off an armed rebellion led by Goldilocks. She even survived a rifle shot to the head, revealing the theory that the more popular a Fable is in legend, the more alive they are in the minds of the mundane humans, the more immortal they are.
Because Goldilocks had been discovered hiding at Bluebeard’s, Bluebeard put Bibgy and Snow under a spell and sent them deep into the Cascade Mountains where Goldilocks could assassinate them quietly. They escaped the assassination attempt while growing closer and Snow said she was willing to give a relationship with Bigby a try. Those good intentions were quickly sidelined when Snow discovered she was pregnant, for which she blamed Bigby despite the fact that both them were entranced and neither remembered anything. Both being professionals of exceptional longstanding, working together was easy but Snow remained distant.
As Bigby went to investigate the sudden appearance of Red Riding Hood in Fable Town, Snow found herself the general of a defending army as a horde of wooden soldiers attacked. While doing well at first, the battle was turning badly when Bigby returned in wolf form and destroyed the army using his “huff & puff”. She and Bigby reconciled briefly. Soon after the battle she gave birth to seven children, only one of which was fully human. Five of the others being more wolf-like and one of which was an invisible zephyr that took her months to discover. Because her children could not pass for human, Snow moved to the Farm to raise them with her sister Rose while Beauty took over as Deputy Mayor. Because of his record as the Big Bad Wolf, Bigby was not allowed on the Farm. Angered that Snow would not leave to raise the children with him in the wilderness and not willing to work under the newly elected Mayor Prince Charming (Snow's ex-husband), Bigby disappeared. Because their zephyr child had accidentally killed a few people trying to feed itself, Snow sent the child to Bigby to care for it lest it be hunted down and killed in the Fable community.
Snow and Rose raised “The Cubs” quietly on the Farm along with help from Bigby’s father, Mr. North or The North Wind, but she kept in close touch with the happenings in Fabletown. In return for succeeding in a highly dangerous mission against the Adversary, Mayor Prince Charming gave Bigby a portion of the Farm as his own. Snow and Bigby were married and now live and raise all seven of their children in Wolf Valley.
