The Shadow's Origin

No one remembers when the Shadow was born.

Some say it wasn't born at all, instead that it followed the humans.

They were the first outsiders to cross Aurora's Veil, drawn by the forest's light and song. They arrived with hearts full of wonder and hands that built, painted, prayed. Aurora loved them for it. She called them kin of curiosity, little sparks walking on two legs.

But where there is light, there is always something watching from behind it.

The humans carried something the forest had never known before: longing that could not be filled. Regret. Envy. Fear of losing what they loved. These were feelings the Hallow could not hold; they were too heavy. So, the forest, in its mercy, tried to absorb them, but the feelings didn't fade. They changed.

They tangled with the Hallow's magic and took on form.

A whisper without shape.

A presence without name.

The Shadow.

At first, it hid inside the humans, curling in the quiet corners of their thoughts. It learned how to move through their hearts.

And when the time came, it sought to spread.

Its first crossing was almost unnoticeable. A woman was crying her tears full of grief she could not speak. A cat, curious and loyal, approached her and licked the tears from her hand. In that moment, the Shadow billowed from the woman's mouth as she opened her mouth to scream at the cat. She screamed and screamed, taking out all of her negative emotions on an innocent being who was just attempting to console her. The cat, in its panic, inhaled the Shadow and ran away to hide.

No one felt the shift right away.

But the cat did. Something strange stirred inside it; a hunger, sharp and cruel, but without need. The forest animals, trusting as ever, still played near it. And then one morning, when the dew was still silver and the sky was still deciding between dawn and day, the cat saw a mouse.

It watched it run. And instead of chasing for food, it chased for pleasure.

When Aurora found the remains, not eaten, not needed, just broken. The truth struck her harder than any storm. The Shadow had learned joy in suffering.

The forest wept that night. Even the stars hid their eyes.

Aurora gathered the winds, the rivers, the roots. She demanded they show her what had happened, and they did: she saw the grief in the human woman, the darkness that rose like smoke and took its first breath through a cat's heart.

That was the moment Aurora understood, the Shadow was spreading like a disease in the Hallow.

Every breath, every touch, every one could carry it.

So she raised the Veil. She banished the humans and their cats, her heart breaking as she did. The Veil shimmered like tears frozen midair, sealing the Hallow away from the rest of the world.

But the Shadow doesn't vanish with distance. It lingers in memory. It finds cracks. It waits.

And though Aurora sealed the gates, she could feel it even then, faint, pulsing, alive.

The Shadow was just outside the Veil.

And it was learning.

So began the biggest war the Hallow will ever have to fight.
