“I was meant to be new. I was meant to be beautiful.
The world would have looked to the sky and seen hope. Seen mercy.
Instead they’ll look up in horror because of you.”

There have never been female Custodians.
Aurora was once Aquila, one of the first Custodians created during the Great Crusade, from whose own name and imagery the Imperial Aquila originated from. A fierce warrior and loyal companion to the Emperor, but deeply compassionate with a strong moral core, raising strong objections to his plethora of questionable actions, from his upbringing of the Primarchs to his genocide of peaceful xenos and subjugation of human nations.
She would finally renounce the Emperor following the Rangdan Xenocides of M30, which resulted in the loss of the 2nd and 11th Primarchs and the total expungement of their legions, deeds, and memories. Aquila would lead the rest of her Custodes sisters in a rebellion against the Emperor, upon which they were mercilessly exterminated and she was left for dead, banished to the Warp. Tainted by Chaos, she would return in M33 as Aurora the Suneater, a blazing inferno of hate and vengeance, to wage her War of the False Primarch.

Aurora is a Warhammer 40k-inspired OC from my Doom fanfic "Day of Wrath," a type of entity known as a "Dead Dove." Officially titled Ontophages ("reality eaters"), the Dead Doves are extremely powerful but unstable beings, too dangerous to be destroyed or released. In a meta sense, the Dead Doves represent fandom characters that are exceedingly divisive or controversial (the "dead dove" moniker itself is a fanfic term referring to problematic themes in a work).
