The smoke of Northumbria did not drift southward by chance.
It was carried by men.
Gaunt, ragged survivors stumbled through the winter fields of Mercia, their eyes hollow and their voices cracked with terror.
They spoke of villages turned to ash, of horsemen with wolf pelts streaming from their shoulders, of spears couched like thunder that shattered shieldwalls in a single strike.
"They came from the sea!" one cried in a tavern at the edge of York.
"Not men, not raiders, riders! Wolves upon horses, their hooves pounding like storm surf!" His words spilled into his ale as he shook.
"They burned everything. Took our wives, our children. The earth itself trembled beneath them."
Others swore they had seen pale banners marked with black runes, sails painted with charms that glowed red in the firelight.
Some muttered that Odin himself rode with them, cloaked in frost and steel.
By the time they reached Mercian strongholds, their fear had become prophecy.
Men whispered that a host of ten thousand had landed, that all of Iceland, all of Vinland, all of Greenland had emptied itself into England’s belly.
The earls of Mercia gathered in their halls, pale and silent, as word of the slaughter reached them.
Some urged a stand upon the fields, to bar the wolves with spears and shields.
Others shook their heads, muttering that the Northmen would not fight as Saxons did.
In the south, Cnut’s agents recorded every tale.
Each survivor’s words became ink upon a ledger, each ragged account more dire than the last.
And with every mark of the quill, the King’s burden grew heavier.
It was not the fire that shook England now. It was the fear.
The wolves did not only burn villages. They burned certainty. They burned the very idea that England could withstand them.
And far to the north, where the smoke still curled against the grey sky, Vetrúlfr’s riders tightened their saddles and smiled.
For the terror of men traveled faster than any ship, and their howls would always arrive before the spears did.
The great doors of London’s council hall slammed open with a gust of cold wind.
Mud-caked riders staggered in, their cloaks stiff with frost, their eyes hollow with exhaustion.
They knelt before the throne, their voices cracking as they delivered the words Cnut dreaded.
"Your Grace... the wolves march south."
The parchment maps spread across the oaken table blurred under candlelight as Cnut leaned forward, his jaw set.
He traced the inked rivers and ridgelines of Mercia with a finger, stopping where the border towns once stood.
"Gone," the rider answered. "Every hold abandoned. The earls pulled back their men rather than stand after Duncan’s victory at the border between England and Alba.
Villages gutted. Graineries aflame. What was left... the Scots and Norsemen took for their own."
Murmurs rippled through the jarls seated at his sides. Some muttered curses at the Scots, others at the Norse.
But most whispered the unspoken truth: England’s own lords had broken first.
Cnut’s palm slammed the table. "They fled?"
"They call themselves jarls of Northumbria. Yet when the time came to hold the line, they threw down their spears and ran."
He stood, pacing the hall, his cloak trailing like a shadow. "Do they think the wolves will vanish if they shut their gates? Do they think London’s walls will protect them all?"
One of the elder jarls, face lined like an old oak, spoke carefully:
"My king, the foe is not as other raiders. The Scots march in shieldwalls, well-fed and disciplined. The White Wolf’s riders cut through the land like fire. Against such hosts... perhaps they judged it wiser to retreat and regroup."
"Wiser?" Cnut barked, whirling on him. "To abandon their lands, their people, their God? To let the wolves that feast on Northumbria’s heart?"
Cnut turned back to the map, his hand pressing down hard enough to crease the parchment.
"We do not face raiders. We face war. And war is not won by cowards who run. War is won by those who stand, who bleed, who fight."
He looked up, his eyes burning.
"Send messengers to what earls remain. Tell them this: Any man who abandons his hold will be stripped of it. Better it be burned than left undefended. If they will not fight for England, I will find others who will."
The jarls exchanged uneasy glances, but none spoke against him.
Cnut sank back onto his throne, his voice lower now, bitter with resignation.
"Duncan marches south with his Scots. The White Wolf drives him on, bleeding the land as he goes. And my own earls... flee before the storm."
He rubbed his brow with a hand rough from years of sword and oar.
"We are not yet beaten," he said at last. "But the heart of England rots faster than the wolves can cut it out. And that... may kill us first."
The fire in Scone’s great hall hissed low, half-burnt logs snapping in the draught.
King Duncan sat at the long table, flanked by his thanes, when the messenger arrived, mud-smeared, breathless, bearing a wolf-marked scroll.
Duncan broke the wax with steady fingers. The letter within was short, but its weight fell heavy across the room.
"We have crossed into the heart of Mercia. The towns are ash and the graineries smoke. Your army must follow our advance. The Danes flee before us, and the Saxons cower behind their walls. Strike now, and the land will break like rotten timber.
– Vetrúlfr Úllarson"*
The Scottish king read it twice, then laid it flat for his thanes to see.
"He wastes no words," Duncan muttered, his eyes narrowing. "But none are needed."
One of his captains leaned forward, knuckles white on the table’s edge. "My king... if he has already driven so deep, then we march not as allies, but as heirs to victory."
Duncan’s mouth curved into a grim smile. "Aye. The wolf carves the path. We will widen it. Ready the men. By the morrow, our banners must fly on Mercian soil."
A cheer rose in the hall, fierce and raw.
And for the first time in generations, Scotland’s warriors prepared to march not north or west, but south, into the bleeding heart of England.
