“Something has entered the Veil from the human world,” Prose says.

The words move through the meadow like a storm.

For a moment, I cannot make sense of them. My mind keeps breaking the sentence apart and putting it back together, trying to make it mean anything else. Willow is in the Veil with the Shadow.

My face goes cold. All the heat in my body rushes to my chest until it burns. My fear becomes fire, and I step toward the Veil.

The crack in the Veil brightens. At first, I think it is Willow answering me. Maybe she hears me. Maybe the green light means she knows I am here. Then I take another step. The crack widens.

“Rosemary,” Prose warns.

I do not stop.

“Then we have to go in,” I say.

“No,” Prose says.

“She is my sister.”

My voice breaks. I hate that everyone can hear how afraid I am. I hate that the whole Hallow is watching me burn when all I want is to run through the Veil and find her. I take one more step. The crack flares. This time, every fawn sees it.

Snow speaks from beneath the glassleaf trees, “It’s growing when Rosemary moves toward it.”

The meadow goes silent. I turn on her. Snow flinches, but she stays. Pale blue light trembles at her chest.

“It did,” she says. “I watched it.”

The crack pulses again. Green light thickens at its edges, sick and deep, like moss left too long without sun. The fireflies closest to it flicker and go out.

“It felt you,” Prose says. “It felt the part of you that would do anything to reach her.”

“That is love,” I say.

“It’s fear and panic,” Prose says. “The same feelings that lead to someone drowning when trying to save someone they love from the same fate—”

Then I hear it.

“Rosemary?”

Everything in me stops. The voice comes from inside the Veil. Small. Frightened. Familiar. My sister’s voice. My legs move before my mind does. The crack widens.

“Stop,” Snow says.

The voice comes again, softer now, “You said you would never leave me.”

The words split something open inside me. I told Willow that once, after our father disappeared. I crawled beside her in the den and promised I would never leave. Now she’s inside the Veil with the Shadow, and I am standing here while she calls for me.

I take another step. The crack opens wider, and something cold spills through it.

Snow walks into the open meadow, “Willow would not ask you to break the Hallow to prove you love her.”

The crack hisses. The voice inside the Veil changes, only slightly. “Rosemary,” it says. “You are the only one who cares enough to come.”

The Shadow presses closer, and a thought comes through in my own voice. If Willow dies, it will be because you stayed.

My hoof lifts from the moss. The crack brightens, hungry and waiting.

Willow’s voice sharpens, “Rosemary.”

But this time, I hear the cruelty underneath. My sister has never said my name like that. That’s not Willow. I put my hoof down.

“No,” I say.

The crack opens wide enough for darkness to bend through, and for one terrible breath, I see what’s inside it. No face. No eyes. Still, I feel it seeing me.

The glimmer stone beneath Prose cracks with a sound like thunder underground. For the first time since Willow entered the Veil, Prose looks afraid. Then the sky answers.

A ribbon of violet light appears above the Veil. Green follows, then gold, then purple so deep it makes the air tremble. Aurora. She arrives as color, as light, as the hush that falls over every living thing when the forest remembers who made it. But this time, her light is not whole. It trembles at the edges.

The moss paths ignite beneath us, then dim almost immediately, as if the ground itself has given more than it can spare. The fireflies relight in a burst of gold, but some fall into the grass afterward, flickering weakly among the roots. The glimmer stone seals its crack with threads of white light, yet a pale fracture remains through its center.

The Shadow recoils, enough to show us it remembers Aurora. Enough to show us it fears her.

Aurora’s voice moves through the torn colors above us.

“Little Ember.”

Every fawn turns toward me. The creator of the Hallow knows what I almost did.

“I’m sorry,” I whisper. “I almost helped it.”

Aurora’s colors soften, and I feel the cost of it in the meadow around me.

“You almost obeyed fear,” Aurora answers. “Then you chose.”

The crack pulses violently. The Shadow does not like that word: chose.

Aurora’s light narrows above the Veil, but it does not strike yet. For the first time, I understand that even Aurora cannot spend light forever.

The Orders stand trembling in the meadow. The Embers burn with scattered, frightened light. The Lumen stare at too many meanings at once. The Vines hold the boundary, barely. The Feathers stay close to the youngest fawns, though they shake too.

We are not trained. We are barely formed. But now I understand why the Orders matter.

My fire can become a door. Snow’s truth can become a blade. A Vine’s care can become a cage. A Feather’s tenderness can become disappearance.

Aurora speaks again, but her voice flickers like firelight in wind.

“I can drive it back from the Hallow,” she says. “I cannot drive it out of every wound it finds. And I cannot keep striking without taking light from the Hallow itself. That is why you must train.”

The words settle over the meadow. The Shadow surges. Aurora’s light meets it. The Veil flashes white-gold. I cannot see Prose. I cannot see Snow. I cannot see my mother. I can only feel the moss beneath my hooves and the red-gold light inside my chest trying to stay steady.

Aurora strikes fully. Her light moves through the crack in one bright line of green, violet, and gold. The Shadow recoils. The crack shrinks. For one breath, I think Aurora will destroy it. Then the Shadow speaks in Willow’s voice.

“Rosemary.”

My whole body goes still. The crack stops closing. Aurora’s light wavers because I waver. The sky above us tears darker at the edges. Aurora is holding the Shadow back, but my fear is holding the door open.

“Please do not leave me,” the voice says.

Every part of me wants to answer, but I understand now. The Shadow does not need to beat Aurora if it can get me to open the door.

“You are not Willow,” I scream.

The crack shudders.

“My sister would not ask me to feed the dark to prove I love her.”

Aurora drives the Shadow backward. The darkness twists once, violently, then slips away from the Hallow side of the Veil, retreating deeper into the realm between worlds. Back toward Willow.

The crack seals until only a thin scar remains, glowing faintly gold at the edges. The colors above the Hallow hang pale and strained. The moss paths are dimmer than before. Several fireflies remain in the grass, their bodies glowing weakly as the Feathers gather around them. The glimmer stone holds, but the fracture through its center is still there.

Aurora has saved us, and it has hurt her. The meadow collapses into silence. Aurora cannot beat the Shadow on her own. She needs us. And now we all understand what’s at stake.

Somewhere inside the realm between worlds, my sister is walking with the Shadow. Aurora has driven it back from the Hallow. But she has not destroyed it. She cannot destroy what we keep feeding.

Tonight, the Orders are no longer just names. They are the beginning of our survival. The Shadow has found Willow, wounded Aurora, and it has learned my name. If I want to save my sister, I cannot only love her fiercely. I have to become strong enough that my love cannot be used against us.
