The forest seemed to swallow sound as effectively as it filtered light. Polly flew low through the branches, following the trail of disturbed moss that marked Astrid and Mikkel's passage. The midnight sun, so dominant over the open marathon route, became a mere suggestion here—golden threads weaving through the canopy like nature's own fiber optics.
"Astrid! Mikkel!" she called, her voice echoing strangely among the trees.
A response came from ahead—not words, but a sharp intake of breath that spoke volumes. Polly burst through a curtain of hanging lichen to find them at the edge of the clearing, frozen in place.
The scene had grown more surreal. The semicircle of entranced runners had expanded to nearly twenty people, all swaying in perfect synchronization. Their eyes remained open but unseeing, fixed on the bunker's dark entrance as if it held the secrets of the universe.
"Don't get too close," Astrid whispered, gripping Mikkel's arm. "Look at their shadows."
Polly followed her gaze and felt her feathers prickle. Despite the midnight sun's angle, the runners cast no shadows at all. The golden light passed through them as if they were merely suggestions of people rather than flesh and blood athletes.
"That's impossible," Mikkel breathed, his scientific mind clearly struggling with what his eyes reported.
"Is it?" Astrid's voice held an odd note. "My grandmother used to tell stories about the war, about this bunker specifically. She said the Germans were experimenting with something here—not weapons, but something stranger. Something to do with the midnight sun itself."
Before Polly could respond, a low humming filled the air. It wasn't quite sound—more like a vibration that bypassed the ears and went straight to the bones. The entranced runners' swaying intensified, and one by one, they began to move toward the bunker entrance.
"We have to stop them," Mikkel said, starting forward, but Astrid held him back.
"Wait," she commanded. "Look at the entrance."
The bunker's doorway, which had appeared solid and rusted shut, was now shimmering like water. Through it, instead of darkness, they could see... another forest. But this one was bathed in moonlight, not the midnight sun. Stars twinkled in what should have been the bunker's concrete interior.
"A portal," Polly whispered, her mind racing through all the impossible things she'd witnessed in her travels. "But to where? Or... when?"
The first runner reached the threshold and stepped through without hesitation. She didn't emerge on the other side—she simply vanished into the moonlit forest beyond.
"The winter forest," Astrid said suddenly. "My grandmother mentioned that too. They called it 'the place where summer never comes.' The Germans thought they could use the midnight sun's energy to create a doorway to—"
Her words were cut short as Mikkel broke free from her grip. "I'm sorry," he said, "but I can't just watch." He sprinted toward the nearest entranced runner—a young woman about his age—and grabbed her shoulders, trying to shake her awake.
The effect was immediate and alarming. The moment he touched her, his eyes went wide and vacant. The insulin kit fell from his belt as his body went rigid, then began the same hypnotic swaying.
"No!" Astrid started forward, but Polly flew in front of her, wings spread wide.
"Don't touch them! Whatever's affecting them, it's contagious through contact."
They watched helplessly as Mikkel joined the line of runners moving toward the portal. His expression had become as blank as the others, his earlier panic and determination erased like chalk from a board.
"We need help," Astrid said, her voice cracking. "The race marshals, the police, someone—"
"They'll never believe us," Polly interrupted. "And by the time we convince them, everyone here will have walked through that portal to... wherever it leads."
The humming grew louder, and Polly noticed something else—the portal was expanding. What had started as a doorway-sized shimmer now encompassed the entire bunker entrance, creeping outward like spilled water.
"It's growing," she observed. "At this rate, it'll reach the marathon route within the hour."
Astrid's face set in determination—the same expression she'd worn when discussing her Boston qualifying time, but now directed at something far more critical. "Then we stop it. My grandmother said the experiments failed because they couldn't control the midnight sun's power. But she also said they had a failsafe—a way to shut it down if things went wrong."
"Inside the bunker?"
"Inside the bunker," Astrid confirmed. "Which means..."
"Which means going through the portal," Polly finished.
They stood at the edge of decision, watching as more runners disappeared into the moonlit forest beyond. Mikkel was almost at the threshold now, his young face serene in its blankness.
"I'm too old for this," Astrid muttered, then laughed bitterly. "I wanted to prove I still had it. Well, be careful what you wish for."
Polly landed on her shoulder, feeling the woman's rapid heartbeat through her feet. "You don't have to do this. I can fly through, find the failsafe—"
"And operate machinery designed for human hands?" Astrid shook her head. "No, we do this together. Besides," she managed a wry smile, "what's a Boston qualifying time compared to saving twenty runners from whatever nightmare they're walking into?"
The portal pulsed, and Mikkel stepped through, vanishing like the others. Time was running out, and more runners were arriving, drawn by the mysterious humming that seemed to bypass conscious thought.
"Ready?" Astrid asked.
"Ready," Polly confirmed, though her every instinct screamed against entering that impossible doorway.
Together, they stepped toward the bunker, toward the portal, toward the moonlit forest that shouldn't exist—hoping that somewhere on the other side lay not just the entranced runners, but the key to bringing them home.
