Biography
Rionach was born in about 1632 at Ilvermorny to Isolt Sayre and James Steward. She had an elder twin sister, Martha Steward and two older adoptive brothers, Chadwick and Webster Boot. She was named after her maternal grandmother.

Rionach was born with magic powers. However, her elder twin was not. Even though Martha was a Squib, she loved her regardless.

When she was a baby, her great aunt, Gormlaith Gaunt, attacked the family. Her parents had been put in to a deep sleep by Gormlaith, but the cries of Martha and her sister woke them. The family were saved by William, the Pukwudgie her mother had befriended several years earlier.

Rionach went on to the teacher of Defence Against the Dark Arts at Ilvermorny School of Witchcraft and Wizardry. She never married because she did not want the Gaunt bloodline to continue. There was a rumour she could speak Parseltongue which attributed to her choice not to marry because she did not want the Slytherin ancestry to continue.
