For Eleanor Potter, it's not her fault she found a scroll full of recipes for pills and how to make them as a second year in the junk thrown out in Knockturn. While she flourished by following it, she did NOT expect to survive solely just from medicine. End result as years go by? Well...her skill would attract powers to her soon and yank her to them!

Lily's Sacrificial Magic given to her daughter as protection will do all means to protect her child. That included disappearing before she became a Horcrux, and changed the fate of two men and plans to shatter in her maturity. Oblivious to it all, she appeared before a man and his retinue.

She was an orphan who somehow ended up a thousand years into the future. Good thing she already knew how to read and write. Survival was also easy since she was used to it and isn't above pragmatic means to do so. But what if she winds up becoming a Tekkadan Member as its Chef? Fem!Harry

She followed Sirius into the Veil...and they ended up in past London, 19th Century because while they are dead in the 1990s, they are alive simply because the Veil doesn't kill. Rather, it gets them lost and ahem, makes them helpless as their wands were 'missing'. So that means they have to do all they can to survive. Lucky Cathy can use magic even wandless huh?

Lucille wised up around that Summer when there's a Special Event in Hogwarts. Considering she has a long string of 'Bad Halloween Luck', she decided to disappear after having forgeries done with Remus' help in Gringotts. She wound up in Japan wherein she got into a whole 'nother level of trouble. Fem!Harry

Giselle Potter greatly resented her relatives and hated their guts. One day, when she came to school and happened upon an upperclassman's comic books and her eyes fell upon a certain page, she asked that person for details out of curiosity. Then in come years later...Giselle was glad she did. Fem!Harry

Serena Potter decided that as long as Fudge is Minister, Britain is a Crapsack World of Corruption and Lies, and a world not worthy of her grief and suffering. She sent Madam Bones her letter of anger and rage after disappearing from Britain entirely, throwing a nation into chaos. Now what did she do during the time she's gone, hmm?
