I know it is a choice because I know her, and because nothing she does on a battlefield is anything but a choice.
She held herself back through the first phase. Not from caution. The dominant dragoness entering the field is a thing you spend once, at the moment it does the most, and the moment it does the most is now — with the reserve breaking, Magnus's line already bending, and his forces beginning to understand that they came the wrong way into the wrong ground.
She comes out of the sun so they see her late.
And when they see her, they see the skull dragon. The bone-white face on the matte black. The coloring that appears in no flight's records anywhere, because it has never existed before her. The size of her, which is not great-wyrm size but is larger every season, the wyrm in her still doing what it has been doing since the submission at the end of her second year.
She comes down out of the high sun into the center of Magnus's faltering line, and the sapphire of her eyes catches the light, and the thing that lands on that battlefield is not the woman who cut Nova's honey bread this morning and held the whole nest in a single look before the letter came.
It is the heir apparent who ran the Purge and walked out.
She hits the center of the line, and the line doesn't bend around her the way it bent around me.
It breaks.
A great wyrm is weight and force, and weight and force can be planned for. What she is cannot. She is acid and shadow and the stone gaze and the four seconds it took her to kill a green dragon, and three years of Shadowcarve, and underneath all of it the thing no drill produces: the will of a creature who decided a long time ago exactly what she is and has never once since been talked out of it.
Magnus's soldiers came expecting a war. They did not come expecting her. There is a difference, and she is the difference, and the center of the line comes apart where she touches it.
She does not fight the way I fight. I am old, and I fight the way old things fight, with economy and patience and the long view. She fights the way she does everything — completely, precisely, the whole of her attention on the exact thing in front of her while the whole of the field stays mapped at the edges, so that she is never only where she is.
She turns the collapse of the center into the collapse of the flank. She reads Magnus's field commander deciding to fall back before he has finished deciding it, and she is already at the ground he means to fall back to. She wastes no motion. She does not spend a life she does not have to spend; I watch her let a whole broken unit flee that a lesser commander would have finished, because finishing them costs her forces and gains her nothing but bodies, and Raven has never once confused bodies with victory.
I hold the ridge, and my part of the field, and I watch the dragoness take Magnus's war apart in the western passes.
I am twelve hundred years old. I have seen a great many things.
I have not seen this before.

By the fourth hour it is over, as over as a first battle ever is. The field is ours. Magnus's forces are in retreat up the passes they came down, the opening he drove for is closed, and the cost of it will be counted for weeks and will be real.
We hold the western passes.
The simultaneous strike went in on Cassius's mark, in the same window, while Magnus's attention and ours were fixed on the fighting. The host network cut. The eggs hit. A year of building landing while the enemy watched the war and not the thing underneath it.
I don't have the full report yet. I know only what came through the bond and the relays: that it went in, that it landed, that what we did in the western passes today was the visible half of a blow whose other half struck somewhere Magnus never thought to guard. Whether it ended Amadeus, I don't yet know.
That report will come.
What I know, standing on the western ridge in the late light with the field held below me and the passes ours, is this. The war has begun, and the first thing it learned about the Marzana heir is that she came the way she comes to everything — ready, precise, entirely herself — and took its opening apart in an afternoon.
She lands beside me on the ridge as the light fades. She shifts, and the skull dragon folds back into the woman, and the thing the enemy reckoned with all afternoon becomes, again, the person I love. There is blood on her that isn't hers. The scar shows above her collar. She is breathing hard, her eyes still bright with the field, and she is looking down at the passes where the last of Magnus's forces are climbing back the way they came.
"Report from Cassius?" she asks.
"Not yet."
She nods and doesn't push. She has learned patience this year, and she will wait for the report that changes everything as long as it takes to come.
"You held the ridge," she says.
"You took the field," I say.
She looks at me. Something passes between us that is twelve hundred years of me and twenty-three of her and three years of the bond that pulled me out of the dark and put me on this ridge beside her on the first day of the war.
Neither of us says anything for a while.
