Don't fear old prophecies. Defy them. We make our own heaven and our own hell.

— Inny to Linus

Madam Lily Minerva Cauldwell (née Leander) (b. 9 November), more commonly known as Inny, is a half-blood witch of the Potter and Leander families, the only daughter of the late Jedidiah and Lattice Leander (née Malfoy-Potter). She is also the younger sister of Sirius and the twin sister of Odysseus, as well as the goddaughter of her aunt Rue. When the twins were merely six years old, their father passed away due to a backfiring spell, leaving the children to be raised by their mother in Godric's Hollow. Having witnessed his death, Inny was left effectively scarred, with the ability to see Thestrals.

Upon attending Hogwarts School of Witchcraft and Wizardry, Inny was Sorted into Slytherin House on account of her observance and analytical flair. Despite being separated from her twin brother, she quickly became best friends with fellow Slytherin Sasha Thorn.


Family lineage

Early life

"Before she hit the world, she was this flame, so bright she burned. I think I knew even then that she was going to be remarkable. I felt it, even when I held her for the first time. I felt it with her brothers too, but with her... I was scared."
Lattice regarding her daughter's early years
Lily Minerva Cauldwell — more commonly known as Inny — was born on the 9th November to Jedidiah and Lattice Leander, a pair of Aurors and two dedicated members of the reformed Order of the Phoenix. She was named after her maternal grandmother, Lily Luna Potter, and Minerva McGonagall, a former Headmistress at Hogwarts School of Witchcraft and Wizardry. Inny was born at 11.55 p.m., while her fraternal twin brother Odysseus was born eighteen minutes later at 12.13 a.m., therefore making the two born on different days. While their parents were holding them in the aftermath of their birth, a lightbulb in the room popped. According to her grandmother and namesake Lily, this was a shockingly precocious display of underage magic, as well as a sign to mark the births of two magically talented children.

The name Lily is an English name, referencing the lily flower and meaning "pure". The lily flower acts as a symbol of beauty and, ironically, innocence and purity.

Minerva is the Roman name of Athena, Greek goddess of wisdom, courage, strategy, and justice, (among other things). The name means "wise."

The name Leander is a Greek baby name, although it can be used as a surname; the meaning of this name is "lion-man", which could perhaps be cleverly attributed to the Leanders' most commonly being sorted into Gryffindor.


Inny: I may die young, but at least I'll die smart.

Inny: Love, love, love... what is it good for? Absolutely nothing. What does it bring any of us but... confusion and bedevilment?

Nancy: You're sad.
Inny: Sad is an emotion specific to those who care.

Wendy: I still don't see what Reilly sees in a girl like you.
Inny: That's because you're not sleeping with a girl like me.

Rose: Lily, you look like hell!
Inny: I just got back.
