The Crimson Sister

Long before The Originals ever began... before Klaus Mikaelson became the monster history feared... before Hope Mikaelson carried the burden of being the Tribrid... there was another child buried beneath the sins of the Mikaelson family.

Her name was Isabella.

The third-born daughter of Esther Mikaelson, Isabella was born under a blood moon during a night the spirits themselves refused to touch. The moment she entered the world, candles died, storms consumed the skies, and whispers echoed through the woods in a language older than magic itself.
Esther called it evil.
But the truth was far uglier.
Isabella was not possessed.
She was simply born more powerful than any witch Esther had ever seen.
And Esther hated her for it.
Terrified that her infant daughter would one day surpass her entire bloodline, Esther committed the ultimate betrayal. Under the crimson glow of the blood moon, she performed a forbidden ritual and murdered her own child before Isabella could even speak her first word.
But death did not claim Isabella.
It transformed her.
Cast into a forgotten abyss beneath the spiritual planes, Isabella spent centuries trapped in darkness, abandoned by the family that should have loved her. Alone with the screams of dead souls and the poison of betrayal, something inside her evolved into something unnatural.
Hatred became her magic.
Pain became her divinity.
