Do you know what my mother used to call me? Dangerous. You're a dangerous girl, Lily. One day, a dangerous witch. And she was right. I am dangerous.

— Lily to Reilly

Lily Minerva Cauldwell (née Leander) (b. 9 November), more commonly known by her peers as Inny, is a half-blood witch of the Potter and Leander families, the only daughter of the late Jedidiah and his wife Lattice Leander (née Malfoy-Potter). She is also the younger sister of Sirius and the twin sister of Odysseus. When the twins were merely six years old, their father accidentally died by means of a backfiring spell, leaving the children to be raised alone by their mother at home in Godric's Hollow.

Upon attending Hogwarts School of Witchcraft and Wizardry, Inny was Sorted into Slytherin House, separating her from her twin who was Sorted into Hufflepuff. She quickly became best friends with Sasha Thorn, a family friend and fellow Slytherin with whom she would maintain a close friendship with for years on. Throughout her school years, Inny was a bright student of inimitable popularity, over time formulating her reputation as a charismatic and manipulative hedonist. She was renowned for her analytical flair and ruthless awareness of the hold she had on others.


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 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 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 Lily, this was a shockingly precocious display of underage magic, and clearly a sign of the births of two magically talented children.

Lily spent her years growing up in Leander Cottage at her mother's home village of Godric's Hollow in West Country, England. In addition to her twin, she had an elder brother Sirius, who was three years her senior.

Reilly Cauldwell


"My girls were meant to be extraordinary. They need to know how proud I am of them."


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.


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