Chapter 1
Bright orange sparks cascaded in showers from beneath the TARDIS console as the Doctor worked feverishly amid the tangled mass of wires and glowing components that formed its navigation system. His shirtsleeves were rolled back to his elbows, revealing forearms dusted with faint grime; his brow was furrowed in fierce concentration, and his sonic screwdriver was clamped firmly between his teeth like a workman’s tool.
With deliberate care, he pinched two fraying wires aside with one hand while reaching deeper into the machine’s innards with the other. His fingers wove through the labyrinth of cables, searching with the ease of long familiarity until they closed around the pair he sought. Drawing them together into a neat bundle, he transferred them to one palm, then pulled the sonic screwdriver from his mouth with a soft click.
He levelled the device at a small, dark purple switch set into the console’s surface.
The familiar, rising electronic whirr echoed through the vast, curved room.
The purple module flared violently, crackling with static and dousing him in another burst of searing sparks.
“Oh, behave,” the Doctor muttered, shaking a stray fleck of embers from his sleeve.
The TARDIS responded with a long, low groan that rumbled through the floorboards like an indignant sigh.
The Doctor raised one eyebrow, glancing up through the metal grating beneath the console.
“If you’d actually landed me in the right time zone and the right century,” he complained, “I wouldn’t have to be doing this at all.”
The old ship answered with another sharp, disapproving hum.
A moment later, Grace Wilson appeared at the top of the entrance steps. She blinked as her eyes adjusted to the warm, honeyed glow of the console room, then froze as another cascade of sparks erupted from beneath the central column.
“Doctor?” she called out.
Without looking up, the Doctor wrestled another handful of wires into place, pressing them firmly home into their connector.
“Down here!” he shouted, his voice slightly muffled. “Just recalibrating the navigation—don’t mind the fireworks.”
Grace sighed, a faint smile tugging at her lips, and settled into one of the coral-soft chairs ranged around the console.
“What is he putting you through, old girl?” she asked gently, leaning forward to rest her hand on the polished wood of the railing.
The TARDIS hummed back, soft and steady, as if in quiet agreement.
Then came an almighty crack.
A blinding flash of light burst from beneath the console, sending a spray of sparks arching high into the air. Grace sprang to her feet as something heavy thudded against the floor below, followed immediately by the Doctor’s unmistakable groan.
She hurried down the steps, gripping the handrail tight as she swung around the corner. There he lay, flat on his back in the narrow space beneath the console, his already wild hair now sticking out in every direction like a dandelion caught in a gale.
He blinked up at her, dazed for a heartbeat before his face brightened.
“Ah,” he said cheerfully. “That was entirely meant to happen.”
Grace stared at him for a long moment, then held out a hand. He took it, and she pulled him effortlessly upright. Standing tall, he towered over her, a sheepish smile playing at the corners of his mouth as he brushed dust and scorch marks from his trousers.
“Honestly,” he said, “that’s not even the worst thing that’s ever happened while I’ve been servicing you-know-who.”
Grace folded her arms and raised an eyebrow.
“Has it never occurred to you,” she said, “that perhaps you’re just not very good at TARDIS maintenance?”
The Doctor’s grin widened. He bent to retrieve his sonic screwdriver, straightened up, and twirled it deftly between his fingers before catching it neatly in his palm.
“I am excellent at TARDIS maintenance,” he declared, with the solemnity of someone stating an immutable law of the universe. “I may not have passed the exam at the Academy—strictly optional, anyway—but I know my own skill set. And my excellence.”
Grace laughed, shaking her head. Ten months of travelling with him, and he could still surprise her, amuse her, and leave her lost for words all in the space of a single breath.
He strode past her, taking the steps two at a time, and returned to the console. Grace followed, her smile lingering.
He set to work at once, flicking switches, pressing glowing buttons, and pulling brass levers with the fluid ease of someone who had tended this machine for centuries.
Then he groaned, slumping his shoulders.
“Still not fixed!”
Grace folded her arms again.
“Like I said,” she said, “you’re not very good at maintenance.”
The Doctor chose to ignore her. Instead he drew one of the curved display screens closer, watching Gallifreyan script dance across its surface as he scanned the readouts. After a moment he glanced over his shoulder.
“So,” he said, “where would you like to go today? Past? Present? Future? Somewhere on Earth, or somewhere far beyond it?”
Grace blinked in surprise.
“You’re asking me?”
The Doctor shrugged, as if this were the most obvious question in all of time and space.
“Of course I am.”
Leaning against the railing, Grace tilted her head.
“You haven’t asked me since the very first day I stepped through those doors,” she said. “Usually I just go wherever you decide we need to be.”
The Doctor’s expression softened.
“Well, I’m asking you now.”
Grace chewed thoughtfully on her lip, then a bright smile spread across her face.
“The 1980s,” she said. “I want to see what it was really like—all the noise, the colour, the music.”
The Doctor’s face lit up with delight.
“An excellent choice.”
He wrapped one hand around the great central lever and hauled it down with theatrical flair. The TARDIS groaned in protest, then her engines roared to life, that familiar, rhythmic wheeze echoing through every corridor as the whole ship lurched into the Time Vortex.
Grace stepped to his side, watching the central column rise and fall in its steady, ancient rhythm.
“Thank you,” she said quietly.
The Doctor released the lever and turned to look at her.
“For what?”
Grace nudged his shoulder gently with her own.
“For showing me all of time and space.”
For a moment the Doctor said nothing at all. He simply smiled, soft and warm.
“Grace,” he said, “it’s my favourite thing in the whole universe to do.”
She stood watching him as he darted around the console, checking dials and tapping panels, moving with boundless energy—every movement proof of the millennia he had spent guiding this impossible machine.
She opened her mouth to speak.
Before she could say a word, the TARDIS lurched violently.
The engines gave a strained, guttural groan, and the entire room shuddered as if struck by a giant hand. Grace lost her footing. She stumbled backward, arms flailing for something to catch hold of, but there was nothing within reach. She hit the metal grating hard, the back of her head striking the floor with a sickening thud.
White-hot pain exploded through her skull. Her vision blurred, swirling into streaks of gold and shadow.
“Grace!”
The Doctor’s voice cracked with alarm. He abandoned the console instantly and sprinted to her side, dropping to his knees. Gently he slid one arm beneath her shoulders and lifted her head to rest on his lap.
“Grace? Can you hear me? Are you hurt?”
She blinked hard, trying to clear the fog from her sight, while a dull, throbbing ache settled behind her eyes.
“What…” she groaned. “What happened?”
The Doctor glanced up as the central column slowed and fell still.
“I’m not entirely sure,” he admitted. “Whatever it was—we’ve landed. But I think we were knocked slightly off course.”
He helped her sit up, then offered his hand.
“Take it slowly.”
She took it, and he pulled her carefully to her feet, keeping his hands steady on her shoulders until he was certain she would not sway or fall.
“What do you mean, ‘knocked off course’?” she asked, rubbing the back of her head.
Once he was satisfied she could stand alone, he hurried back to the monitors. Gallifreyan symbols raced across the screen as he studied them, his brow drawing tight.
“It happens,” he said. “Debris gets pulled into the Vortex. Asteroids, the remains of old starships…” He paused, his voice quieter. “Other things, too.”
Grace frowned.
“What kind of ‘other things’?”
The Doctor looked at her for a long moment, but said nothing more. Instead he walked to the railing where his brown pinstriped blazer hung, pulled it on, and buttoned it neatly. Then he flashed her his brightest, most reassuring grin.
“Shall we go and find out exactly where we’ve ended up?”
Grace hesitated.
“Is it safe?”
The Doctor considered the question, then nodded.
“As safe as crossing a busy road.”
Grace gave him a look of deep doubt as she followed him toward the double doors.
“Oh,” she muttered under her breath, “that’s so very reassuring.”
The Doctor only smiled to himself as he wrapped his hand around the brass handle and pulled.
Blinding white light flooded into the console room. A cool breeze drifted over the threshold, carrying the sharp, sweet scent of lemon and wild lavender, tangling in Grace’s curls as she squinted against the brightness. Without hesitation, the Doctor stepped out into the open air. Grace followed.
As her eyes adjusted, she stopped dead in wonder.
The sky above stretched endlessly, a vast tapestry of deep violet streaked with ribbons of lilac and soft rose that drifted like smoke across the heavens. Two suns hung low on the horizon: one glowing rich amber, the other a brilliant molten gold, their combined light gilding great clouds of shimmering dust that drifted across the purple expanse.
The land was just as breathtaking. Rolling fields of sapphire blue and vivid gold stretched to the edge of sight, rippling in the wind like the surface of an endless ocean.
It was beautiful—utterly, impossibly beautiful.
“Where are we?” Grace whispered.
The Doctor held a finger aloft, testing the breeze, then nodded to himself and turned back as she drew the TARDIS doors shut behind her.
“Planet Caster Blue,” he announced. “Current population: zero. Temperature: a very pleasant twenty degrees. And…” He sniffed the air dramatically. “…there’s a fair chance of rain later this afternoon.”
Grace shook her head, smiling. She still had no idea how he did it—how he could know exactly where they were, and what the weather would be, just by stepping outside and feeling the air. It was just one of those things about the Doctor that she had long since accepted as simply… him.
She walked to stand beside him.
“So,” she said, glancing out over the silent fields, “is it really safe?”
The Doctor tilted his head, looking entirely innocent.
“Now,” he said, “would I be this calm if I didn’t think it was?”
Grace folded her arms.
“You said exactly the same thing about New York in 1912.”
His smile faltered, just for a moment.
“About five minutes before the ghost ship Titanic appeared in the middle of Fifth Avenue,” she added.
The Doctor cleared his throat.
“…Fair point.”
Grace laughed. He, though, was already gazing out across the empty hills, curiosity sparkling in his eyes.
“Still,” he said, clasping his hands behind his back, “this feels different. And besides…” He drew a deep breath of the scented air. “Planets without people are almost always the most interesting ones.”
Grace sighed, amused and resigned.
“That is exactly what I was afraid of.”
They set off across the rolling landscape, the blue-and-gold grass swaying around their ankles. The Doctor talked almost nonstop as they walked, explaining that Caster Blue had once been home to a whole civilisation of cloud-beings—creatures made of living mist who had floated through its skies for millions of years. As the twin suns slowly burned hotter, they had simply, gently, evaporated into the atmosphere, leaving the world to silence.
“It was rather tragic,” he said, hands deep in his pockets as he bounded over a small rise. “Not violent, not dramatic—just… inevitable. One day they realised it was time to go, gathered up all they could carry, and drifted away into the stars. Lovely creatures, by all accounts. Terrible singers, though.”
Grace smiled to herself. She could listen to him talk about the universe forever—every word brimmed with such warmth and wonder. He never just walked: he skipped, spun round mid-sentence, gestured so wildly it was a miracle he stayed upright. His joy was infectious.
“Oh!” he cried suddenly, pointing toward the horizon. “There should be a city nearby—abandoned now, of course. Built entirely of crystal. Unless time’s playing tricks again.”
“That’s very comforting,” Grace said dryly.
They walked on until the ground simply ended.
A cliff edge.
The Doctor stopped just short of the drop. Far below, deep violet water shimmered beneath the twin suns, waves breaking softly against rocks that looked no bigger than pebbles. He turned slowly in a circle, scanning the skyline, then pulled out his sonic screwdriver and aimed it at the empty air between their cliff and another facing them across the chasm.
The familiar whirr hummed through the stillness.
“Thought so,” he said.
And then he stepped forward—straight into thin air.
“Doctor!” Grace lunged to catch his arm, then froze.
He had not fallen. He stood perfectly still, several feet beyond the edge, as if the empty air had turned to solid ground. He looked back at her, grinning.
“Anti-gravity stabilisers,” he began cheerfully. “They generate a compressed atmospheric field that permits—”
Grace stared at him.
He paused.
“…It’s an invisible bridge.”
“That,” Grace said flatly, “would have been the perfect place to start.”
“I do tend to get carried away with the explanation,” he admitted.
Grace took a deep breath and edged one foot out over the drop. Her Converse met something firm and unyielding. She shifted her weight, testing it, and the invisible surface held fast.
“See?” the Doctor called. “Nothing to worry about.”
Grace shot him a look that said she disagreed entirely, but stepped out after him. Every step made her heart beat faster; more than once she glanced down, seeing only the abyss beneath her feet, and quickly fixed her gaze on his back instead. Only when she stepped onto solid rock on the far side did she let out the breath she had been holding.
“I’m beginning to think,” she muttered, brushing imaginary dust from her jacket, “that travelling with you is going to shorten my life by years.”
The Doctor beamed.
“Oh, almost certainly.”
Grace stared at him.
“You weren’t supposed to agree with that.”
They followed a path of bright white stone that wound through the hills, where hardy little plants pushed through the cracks, their leaves a vivid mix of emerald and gold. The breeze tangled Grace’s hair around her face, and she brushed it away for what felt like the hundredth time. Without warning, the Doctor stopped so abruptly she walked straight into his back.
“Oof.” She rubbed her shoulder. “Doctor!”
He did not seem to hear. He stood perfectly still, staring ahead.
“That’s not right,” he murmured.
Grace looked past him. Half-buried in the long grass lay the wreck of a spacecraft. Its polished chrome hull had dulled to a dull grey, and long, dark orange viewports ran along its side. Great gashes split the metal plating, and twisted debris lay scattered across the ground; vines and alien flowers had crept over the ruin, slowly reclaiming it for the planet.
“It looks as though it’s been here for centuries,” Grace said quietly.
The Doctor tilted his head, his expression growing serious.
“That’s a Dominator vessel.”
Grace frowned.
“Is that bad?”
“Potentially.” He narrowed his eyes at the wreckage. “Let’s hope there are no Quarks still aboard.”
“Quarks?” Grace asked. “What are they?”
“Robotic soldiers,” the Doctor said. “Servants of the Dominators. Small, relentless, and thoroughly unpleasant. I haven’t seen one in two hundred years or more.” He tapped the hull lightly with his screwdriver. “But this ship crashed a long time before that—at least two centuries, maybe three. Those vines take a hundred years just to get that thick; this level of corrosion takes another hundred.”
Unease curled in Grace’s stomach.
“So whatever happened here…”
“It was a very bad crash,” the Doctor finished softly.
For a long moment neither spoke. The wind sighed through the broken hull, making a low, mournful whistle that echoed across the valley. Then the Doctor’s smile returned.
“Which means…”
Grace already knew what was coming.
“We’re going to investigate,” they said in unison.
The Doctor chuckled. “You really are getting to know me.”
Grace sighed, but her eyes were bright.
“I was afraid of that.”
Together they moved cautiously toward the silent wreck, the long shadow of the ancient ship stretching out before them across the white stone.
