The ground trembles before I see them.

Not the wild thunder of Orc feet — I know that sound too well. This is measured. Disciplined. A cadence born of drilled ranks and a will that does not break under fire.

I turn toward the eastern ridge as the smoke thins.

Silver crests the hill.

Warriors rise into view in ordered lines, armor catching the pale light like frost caught mid-fall. Moonsilver — forged thin and bright — etched through with veins of mithril that glimmer faintly beneath ash and blood. Long spears lift as one, a forest of points angling forward with terrifying precision.

A legion.

Quiet.

Deadly.

At their head rides a figure that makes the world seem to draw tight around her.

She crests the ridge astride a great white elk, antlers sweeping back like living ivory — Seraphin. A white cloak streams behind her, unmarked and unadorned, stark against the smoke. Her armor fits her like a second skin, moonsilver traced with mithril runes that catch the light with every movement.

Her hair lies loose down her back — white as moonfall — unbound despite the battle.

In her hands she bears a spear.

Not ceremonial. Not ornamental.

A weapon.

The battlefield exhales.

Dáin Ironfoot lets out a sharp, incredulous laugh beside me.

“By Mahal,” he says, eyes bright beneath his helm. “She answered.”

I tear my gaze from the ridge just long enough to demand, “Who is that?”

Dáin doesn’t look away from the field.

“My ally,” he says simply. “And if we’re still breathing by nightfall, you’ll thank me for sending word.”

Before I can press him, a low voice cuts in at my other side.

“Rivers?”

Dwalin has gone still.

Not braced. Not coiled.

Focused.

“Rivers,” he repeats, slower now, eyes locked on the rider as the legion begins its descent. “From Azanulbizar.”

I turn sharply. “You know her?”

“Aye,” Dwalin says. “I do.”

The silver line breaks — not into chaos, but into motion. Shields angle. Spears dip. The legion pours downhill like a controlled avalanche, slamming into the Orc flank with brutal efficiency.

And she is already among them.

No — ahead of them.

Seraphin rears, hooves striking down an Orc as she drives her spear forward. The weapon flashes — clean, precise — and an Uruk falls before he can scream. She pivots in the saddle, cloak snapping, spear haft catching a blade before she rips it free and strikes again.

Orcs die where she passes.

Not hacked. Not bludgeoned.

Ended.

Dáin nods once, grim satisfaction cutting through his usual mirth.

“She’s here because Azog is,” he says. “I sent word when the banners went up. Told her the white scars of the north had stirred again.”

He bares his teeth in something close to a smile.

“She doesn’t forget her enemies. And she doesn’t leave debts unfinished.”

Dwalin’s jaw tightens.

“She nearly had him once,” he says. “At Azanulbizar. Drove Azog back hard enough the snow ran black. Took an Uruk captain through the chest like it was nothing. Didn’t falter when the line folded.”

His eyes track her as she drives Seraphin straight into the press, elk and rider moving as one.

“She earned her place that day.”

Dáin snorts softly. “Aye. And when I called this time, she didn’t ask for banners or gold. Just asked where he’d show his face.”

The name Rivers settles into my chest like a stone dropped into deep water.

Rivers.

I watch her spear rise and fall, watch the legion bend around her like a living thing, and something cold and sharp coils behind my ribs.

Who is this woman who rides into war without crown or trumpet, who commands a legion by motion alone, who carries a spear Dwarves remember by name, who nearly ended Azog once — and has come again to finish it?

And why does my blood tell me that the mountain has just recognized not a guest, not an ally alone, but a force the war itself has been waiting for?
