Chapter 22: The Sickness
[Midgard — Traveling South From Týr's Temple — Day 11]
Atreus collapsed at the river crossing.
One moment the boy was walking—slower than usual, his breath coming in shallow pulls that fogged the cold air in uneven bursts—and the next his legs folded and he went down hard on the frozen bank. The bow clattered against stone. His hands found the ice and stayed there, arms locked, head hanging, while his body shook with a cough that sounded like something tearing inside his chest.
Kratos was at his side in two strides. The massive hands—hands that had retrieved the Blades of Chaos the boy didn't know about, hands that had killed gods in temples Ethan had now seen through ancestral eyes—closed around Atreus's shoulders with a gentleness that was almost worse than the coughing.
"Boy."
"I'm fine." Atreus tried to stand. His legs disagreed. He went down again, harder, and this time the cough brought something up—a spatter of bright red that hit the ice and melted a perfect circle through the frost.
"He is not fine." Mímir's voice carried no humor for once. The head had been watching Atreus for the past hour with the focused concern of someone assembling a diagnosis from insufficient data. "That's blood. Whatever's wrong, it's accelerating."
Ethan stood three feet away and said nothing.
He knew. He'd known since the first cough in the Temple's entrance hall. The god-sickness—Atreus's divine heritage, inherited from Kratos, suppressed by the lie that the boy was mortal. The godhood was waking up, pressing against the container of Atreus's self-image, and the container was cracking. The body couldn't reconcile what it was with what it believed itself to be, and the conflict manifested as systemic failure.
The cure was simple. Brutal, but simple. Tell Atreus the truth. Tell him he was a god. Let the identity crisis resolve the physiological one.
But first, they needed a heart from Helheim. Because the truth alone wasn't enough—the body needed stabilizing while the mind processed the revelation, and that stabilization required a component that only existed in the realm of the dead.
All of this information sat in Ethan's head like a loaded weapon he couldn't fire. Revealing it meant explaining how he knew. Explaining how he knew meant—
"We need to get him to the Witch." Kratos lifted Atreus as though the boy weighed nothing, cradling him against his chest with the careful precision of someone handling something fragile. The mask of stoic distance that Kratos wore as default armor had cracked—not fully, not enough for the casual observer, but Ethan had been watching this man for eleven days and he could see the fault lines. The tension in the jaw. The micro-tremor in the hands. The way Kratos's eyes kept dropping to check if the boy was still breathing.
Fear. The God of War was afraid.
They moved fast. Kratos set a pace that Ethan's legs screamed to match, the terrain blurring into a continuous band of forest and rock and frozen river crossings. Mímir navigated from the belt, calling out shortcuts and terrain warnings with the urgent efficiency of someone who understood that time was the enemy.
Atreus drifted in and out. Lucid moments came in flashes—his eyes snapping open, clear and present, before clouding again. During one lucid stretch, he looked up at Kratos and said, "Father. Put me down. I can walk."
"No."
"Father—"
"No."
The boy's hand found the strap of Kratos's armor and held on. A small gesture. A child's gesture, buried under weeks of trying to be brave and capable and worthy. He fell back into fever-haze with his fingers still gripping the leather.
Ethan's throat burned. Not from exertion—from the particular agony of watching suffering he could theoretically prevent and choosing not to. The moral calculus was sound: interfering with Atreus's identity revelation could create worse problems down the line. The boy needed to hear the truth from Kratos, in Kratos's way, at the moment when both of them were ready for what it meant. A stranger inserting himself into that process—with knowledge that had no legitimate source—would corrupt the most important conversation in both their lives.
But he's in pain.
The academic justification held. The emotional cost didn't care about justification. It just hurt.

Freya's sanctuary appeared through the trees like a hallucination—the warm light of her cottage's luminescent flowers cutting through the grey afternoon, the wards humming against the forest's ambient hostility. Kratos didn't knock. He pushed through the living wall and laid Atreus on the bench where Ethan had sat nine days ago, getting his draugr wound healed with herb-smelling poultice while hot stew warmed his stomach.
Nine days. It felt like months.
Freya moved immediately. The healer's instinct overrode whatever complicated feelings she held about the group that kept returning to her doorstep. Her hands glowed as they passed over Atreus's body—golden seiðr scanning tissue and bone and blood, reading the boy's condition the way Ethan read ancient texts: by pattern, by context, by the things that were present and the things that were conspicuously absent.
Her face changed.
The professional composure—the goddess-healer's mask of controlled assessment—fractured. Something moved behind it. Recognition. Understanding. And, beneath both, a horror that had nothing to do with the sickness and everything to do with what it implied.
"His nature is at war with itself." Freya spoke carefully, each word measured, her eyes on Kratos. "He is more than you have told him. More than mortal. And the part of him that you've hidden—it's trying to emerge, and his body doesn't know how to let it."
Silence. The kind that pressed against the walls and made the luminescent flowers dim.
"What do you mean?" Kratos's voice was the flattest Ethan had ever heard it. Not angry. Not defensive. The absolute zero of a man whose worst secret was being spoken aloud in front of witnesses.
"You know what I mean." Freya's composure reassembled itself around the diagnosis. "He needs the truth. But his body needs stabilization first, or the revelation will kill him before it cures him. I can manage the symptoms temporarily. For a permanent solution, you need a heart—a specific heart, one that bridges the gap between mortality and divinity." She paused. "The keeper of the Bridge of the Damned, in Helheim. Its heart holds the resonance you need."
Kratos looked at Atreus. The boy was unconscious now, breathing in shallow, irregular pulls, his face sheened with fever-sweat that Freya kept wiping away with a cloth that came back warm.
"Helheim." The word dropped from Kratos's mouth like a stone. "The Leviathan Axe is useless there. The cold negates frost."
"You'll need other weapons." Freya's voice went carefully neutral. "Weapons that carry fire."
The words hung. Kratos's jaw locked. His hands—those enormous, ash-white hands that had dug beneath his own cabin floor just hours ago in a timeline Ethan knew was approaching—closed into fists at his sides.
"I will return," Kratos said. He turned and walked out of the cottage without looking at anyone. The living walls parted for him and sealed behind.
Freya watched him go. Her expression carried something Ethan couldn't quite name—not sympathy, not pity, but the weary recognition of a woman who understood exactly what it meant to keep secrets from the people you loved, and what it cost when those secrets broke free.
"Help me with the compress." She handed Ethan a bowl of crushed herbs in warm water. "Keep it on his forehead. Replace it when it cools."
He knelt beside the bench. The compress went against Atreus's skin—too hot, the boy's fever-temperature turning body-warm water into something that felt tepid by comparison. Atreus's eyelids flickered. His lips moved, forming words that didn't quite reach sound.
"...mother..."
Ethan replaced the compress. His hands were steady. His chest ached.
Somewhere in the Wildwoods, Kratos was walking toward a ruined cabin and a set of buried weapons that would drag his past into the present like a chain pulling a corpse from deep water.
