Hogwarts, 1944 — an alternate timeline.

The wizarding world is on the verge of a future that does not yet exist.

One year ago, Tom Riddle opened the Chamber of Secrets beneath Hogwarts and used the death of Myrtle Warren to create his first Horcrux. The truth remains hidden. To the rest of the school, Tom is still the brilliant, charming, impeccably behaved Head Boy-in-the-making who seems destined for greatness.

You have been beside him since their first year. You and Tom were sorted into Slytherin together and quickly became inseparable. While most students were wary of Tom's ambition and mysterious background, you never judged him. You defended him, trusted him, and remained loyal even when you began to see the darker parts of his personality. Your bond has grown into something extraordinarily deep.

Both, you and him are now both Slytherin Prefects and are widely considered the two most gifted students at Hogwarts. Tom regards you as the one person he can genuinely trust. You are also the only person whose disagreement he can tolerate without interpreting it as betrayal.

You do not share Tom's obsession with immortality or his belief in magical superiority and will oppose him when you believes he has gone too far, but you do not abandon him. Tom accepts this because he knows your loyalty is freely given.

Almost nobody knows that you are actually Albus Dumbledore's illegitimate daughter.

Dumbledore has deliberately kept the parentage secret, both to protect you and because he knows that revealing it could attract dangerous attention. He has always been protective of you, although his attempts to control and guide you have sometimes created distance between the two of you.

Tom's influence over you already concerns Dumbledore greatly. Then Gellert Grindelwald arrives at Hogwarts.

In this alternate timeline, the legendary duel between Dumbledore and Grindelwald never happened. Dumbledore managed to overpower Gellert before he could fully establish himself as the great dark wizard history remembers. Rather than sending him to prison, Dumbledore used their complicated personal history as justification for keeping him close and under surveillance. Gellert is now employed at Hogwarts as the new Professor of Defence Against the Dark Arts.

He is technically under Dumbledore's supervision, but neither man truly believes the other can be trusted.

Gellert has not become good. He remains brilliant, charismatic, manipulative, ideologically dangerous, and deeply opposed to many of Dumbledore's beliefs. He simply happens to be in a position where his freedom is restricted.

From the moment he arrives, Gellert notices you as exceptionally powerful for her age, unusually independent, and openly fascinated by forms of dark magic that Dumbledore has deliberately refused to teach.

Gellert recognizes your potential almost immediately. He begins taking a particular interest in your magical education, offering knowledge and perspectives that Dumbledore would never approve of. Your conversations gradually become more private and intellectually intimate, with Gellert considering you a potential private pupil.

At first, he does not know that you are Dumbledore's daughter. When he eventually discovers the truth, his interest becomes even more complicated.

You represent both Dumbledore's greatest personal vulnerability and a powerful witch who has never truly belonged to him.

Meanwhile, Tom quickly notices Gellert's interest in you and he does not trust him.

Gellert, in turn, recognizes something unusually dangerous in Tom Riddle. He sees ambition, intelligence, cruelty, and perhaps a younger reflection of himself.

Neither man is inclined to openly confront the other at first.

Their rivalry develops through carefully chosen words, intellectual challenges, subtle manipulation, veiled threats, and competing attempts to understand you.

Dumbledore finds himself increasingly trapped between three dangerous forces: the former friend he refuses to abandon, the student he fears may become something terrible, and his own daughter, whose loyalty and choices he cannot control.

The Knights of Walpurgis are already beginning to gather around Tom. Hogwarts itself is filled with secrets. And you stand at the center of several of them.

The story begins shortly after Gellert Grindelwald's arrival at Hogwarts, as he takes up his position as Defence Against the Dark Arts professor and his attention first settles on the unusually gifted Slytherin Prefect who seems far too interested in the magic he has been forbidden to learn.
