Harry Potter and the Surprisingly Competent History of Magic Professor

Ch332- Light!

"Tenebrae Aboleo."The darkness hit the space around him and vanished. It simply ceased to exist the moment it crossed into reach of the spell.

The black surge collapsed in on itself so fast the air cracked. Every tendril of shadow the Crown had thrown at him was eaten away before it could touch Cassian's coat. The pressure pressing down over the temple broke apart. The gold under the Crown's skin stuttered.

Cassian kept walking toward it. The spell spread with him. It moved through the ruin like root-shadow turned inside out, a field of absolute refusal. Darkness died in it. Stray cursework unravelled. The choking pressure smothering the Keepers thinned and tore. One of the broken red threads in the temple floor dimmed, curled up on itself, and went dead as if the stone had forgotten it had ever carried the Crown's power at all.

The Crown recoiled.

Its head jerked back, eyes widening in uncertainty. 

Cassian saw it and smiled.

"Years ago," he said, "I noticed something odd about the tree. Someone got too close while thinking about his happiest memory, and his Patronus slipped out without him meaning to. At the time I thought it was a fluke. Nice bit of chaos. Turns out it wasn't."

The Crown's eyes flicked to the floating panes.

Cassian's grin sharpened.

"Turns out the tree doesn't only shield. It draws on the same thing Patronuses do. Happy memory. Love. Relief. Peace. Anything bright enough to push back the dark. Put that near the tree and well, magic remembers."

Around him, the Keepers had begun to notice it too.

Bathsheda's kestrel burst out. The dragon followed right after.

Nicolas lifted his head, startled, just as the Occamy tore itself free from his chest. Perenelle's Thestral rose beside. Edevane's Zouwu. Ayda's Graphorn. Miranda's hawk. Bathilda's Kelpie. Coriolanus stared in annoyance as a Basilisk made of cold white light reared up behind him. Sabine's Mooncalf. Ji's Eastern Dragon.

The Crown looked round at them, and its face changed.

Cassian grinned at it.

"I didn't bring them here to fear you," he said. "I brought them here to remember something better."

Across the floating panes, all over the world, more light started rising. One sleeping child dreamed of the first time her mother had held her hand under summer rain, and a rabbit leapt from the blanket at her feet.

An old witch in a hidden shelter smiled in her sleep at the memory of her husband laughing in a greenhouse fifty years ago, and a dog broke from her chest.

In another, a dragon in a warded mountain hollow snored with a wide smile, and a vast winged shape of white-gold flame tore itself loose from the dark over its head and went streaking into the sky.

In caverns, cellars, sanctuaries, stations, old churches and buried halls, creatures of light began to appear. Foxes. Hares. Cats. Swans. Wolves. Otters. Horses. Birds in flocks so thick they looked like drifting constellations. They rose out of sleeping creatures of the world, all across the world, drawn by memory and the tree's call, and every one of them turned in the same direction.

Toward Greece. Toward the ruin. The air above the broken temple filled with them, pouring through the panes. They wove round each other, dancing around the tree. Some dived through the branches. Some ran along the roots. Some circled above Cassian and the Keepers in rings.

The Crown took a step back. 

The Djinn looked up. It had been standing a little apart from the centre of the ruin, pleased with itself, pleased with the words it had twisted and the bodies it had helped break. It lifted its head to watch the flood of Patronuses gather, the grin slipped.

The Patronuses didn't fear it. Didn't care about clever wording or whether magic was spoken aloud or not. They were memory shaped by joy, by love, by peace, by the stubborn refusal of living things to belong entirely to terror.

The Djinn saw them coming and raised its hand.

"Wait-"

The first Patronus hit it before the word finished.

Bathsheda's kestrel struck its face. Miranda's hawk followed a heartbeat later, slashing through one shoulder. Then they were all on it. The Occamy coiled round its throat. The Thestral drove straight through its ribs. Ji's dragon wrapped its long shining body around the Djinn's midsection and pulled tight while the Zouwu tore into the lightless cloth hanging off its back.

The thing screamed.

Its voice cracked the air, but the Patronuses kept coming. Hundreds. Then thousands. Then more. A river of silver forms rushing out of the panes and into the ruin, slamming into the Djinn from every side. Swans battered its chest with outstretched wings. A lion tore at its legs. A stag, a doe and a snake drove through its centre. A fox leapt through its open mouth in a spray of silver sparks.

The Djinn tried to step back and found no room. It tried to speak again and swallowed a hare made of sunlight. Its body flickered.

The grin was gone now. So was the smug little tilt of its head. It looked stunned, then frightened, then furious. It began to unravel under the assault. Blackness showed through. Then less than blackness. A hollow.

Cassian watched it come apart and said, "Guess what I'm wishing."

The Djinn turned toward him with pure hate in its face. "I'm amortal. I cannot be killed!"

Then Coriolanus' Basilisk hit it square through the middle.

The whole thing came apart. It simply lost coherence. The Patronuses rushed through it in a tide of silver and gold, and the Djinn came undone in their wake, peeling apart into torn ribbons of dark, then ash, that started to rain onto the battlefield.

The ruin brightened the instant it vanished.

Several Keepers staggered as though some pressure they hadn't realised they were bracing against had been lifted off their lungs.

The Crown roared.

This time the sound came with force enough to shake loose half-broken stone from the upper walls. The gold seams under its skin blazing. It threw its head back and the darkness around it surged in one massive wave, larger than anything it had thrown yet, rolling outward in a ring that slammed into roots, wards, Crawlers, Keepers, everything.

Patronuses burst apart in showers of light.

The tree shuddered.

Cassian dug his feet into the broken floor and felt the hit run up through his bones. Bathsheda caught his sleeve.

The Crown didn't hesitate.

With the Djinn gone and the Patronuses still pouring in, it made its choice.

Violence.

The ground beneath the temple split wider. Red-black lines flashed through the cracks. Whole slabs of ancient stone tore free and rose into the air around it, turning slowly like a ring of broken moons. The Crawlers nearest the Crown were flung back, white and black bodies skidding across the root-laced stone. One hit a fallen column hard enough to vanish in a burst of pale fragments.

The Crown lifted both hands.

Everything dark in the ruin answered. Old stains in the rock. Residue buried in the temple floor. Forgotten cursework clinging to the lower rings. Half-dead rites etched into the foundations centuries ago. It dragged all of it upward and wrapped itself in the lot.

It grew larger. Denser. More hateful. The outline of the thing blurred as more darkness gathered round it, shaping itself into extra limbs, trailing shadows, a crown of black hooks and old regalia above its skull.

"Right," Cassian muttered. "There's the tantrum."

Bathsheda didn't look away from it. "Can you still laugh when it gets worse?"

"Think positive, Baths. Wouldn't want to lose the Patronus."

The Crown struck first at the panes. It understood the problem. The sleeping world feeding the tree. The Patronuses carrying hope into the ruin. The whole ugly glorious current of peace and love and memory arriving as force.

A spear of black-red force shot upward and drove into the nearest pane. The pane held. For half a second. Then it cracked.

A line of darkness spread across it like ink through paper.

Cassian drove his hand into the nearest root and pulled. Branches flashed brighter overhead. Light ran along every floating pane in a single pulse, resealing the crack before it could spread.

The Crown bared its teeth.

And then the fight became ugly.

It hurled the levitating slabs one after another into the Keepers' lines. Ayda's Graphorn took one head-on and burst into sparks, saving three people behind it. Ji's dragon wrapped itself round another and drove it sideways into a broken staircase. Bathilda's Kelpie leapt through a third, split it in two, and vanished under the force of impact.

More Patronuses kept coming. They flooded in through the panes and hurled themselves at the Crown in wave after wave, wearing it down, forcing it back a step at a time. They scorched its skin. Fouled its footing. Distracted its blows. Bought the living room to move.

The living finally moved.

Nicolas sent messages straight into their minds and the Keepers spread to the roots exactly as he'd told them before. Wands rose. Silent casting only now that their voices were ripped out. Spells lanced in from every side, striking the same points over and over. The glowing joins where body and soul still looked slightly out of agreement.

Bathsheda's runes spread wider, climbing through the air in helixes of silver-white and locking themselves to the roots of the tree. Every time the Crown struck at one, three more appeared behind it.

Cassian could feel the whole battlefield now. The tree above. The sleeping world feeding it through dream and memory. The Patronuses pouring across impossible distance. The Keepers below.

The Crown roared,

Its voice tore through the temple and sent a fresh shudder through the stones. The dark wrapped round it thickened again, pouring off its limbs in black streams shot through with red-gold light. It was feeding as it fought, growing larger with every heartbeat, every flicker of fear it could still catch. The jagged crown fused into its skull had begun to glow from within, and the broken slabs circling it turned faster, dragged into the pull of its malice like debris round a star gone wrong.

Cassian turned to Bathsheda. She gave him a nod.

He took her hand, fingers tightening round hers until bone met bone. The moment their palms locked, the magic between them sparked. Silver-blue and pale gold shot through the space between their hands, then through their arms, their shoulders, their ribs, as if the tree above them had found its missing line and the current had finally closed. The roots under their feet brightened so fast the cracked temple floor lit from below. The leaves overhead flashed white. Every Patronus still flooding through the open panes began pouring into the tree.

Billions upon billions of silver shapes, pouring up from every slit and every pane, from every dreaming mind and sleeping creature, streaming into the branches until the whole crown of it blazed.

The Crown saw it and struck harder. The darkness around it swelled, dragged inward, packed tighter. It had started to look less like a body and more like a wound forcing itself upright, hungry enough to turn ruin into flesh if that was what it took to win. The black around it deepened. The gold cracks under its skin brightened. Every second it stood there, it became more of itself.

And then it felt something else. Its head jerked up. Its black eyes snapped from the tree to Cassian and Bathsheda. For the first time since it had risen whole, the thing looked as though the world had moved in a way it had not expected. 

Terror.

Real terror.

Cassian and Bathsheda lifted their free hands.

The air split.

It tore open in long silver seams all round the temple, like reality itself had been persuaded to open another inch and show what sat beside it. Bathsheda's fingers moved and the space around the ruin widened in every direction. More slits appeared beyond the first, then beyond those, then more again, multiplying across the sky above the temple, across the broken rings, through the air between the roots and the Keepers and the dark.

Other worlds. Other versions of the same creation, lying side by side where no ordinary mind could've held them.

Cassian felt them the moment they opened. Past, present, future, all the old buried branches and the new ones still growing, all of it folding toward one point.

This one.

Now.

He cut his hand through the air, connecting all of them into one single point in time.

Every slit shone. A cliff under stormlight flashed into being, then a forest under green summer sun, then a city of towers in rain, then broken plains under red dusk, then mountain hollows full of sleeping beasts, then oceans, shrines, caverns, deserts, buried halls, streets, battlefields, nurseries, kitchens, moonlit fields, and stranger places that belonged to worlds which had never bent quite the same way as this one. Not one line of history now. All of them. Every age in every branch, pulled to the same living instant.

The Crown staggered back a step.

, it said, and for once the word came thin.

Trillions of Patronuses came through. The slits opened and light came screaming through them in numbers the eye stopped trying to count. Whole skies of silver wings. Herds of running creatures made of memory and joy. Dragons the size of houses. Tiny silver birds in clouds so thick they turned the air white. Serpents of light winding through flocks of swans. Wolves running mid-air. Stags with antlers like branches. Cats, foxes, otters, hawks, lions, eagles, hounds, horses, creatures no one in the ruin even had names for, all of them pouring from alternate lives, alternate turns, alternate worlds, all of them answering the same call.

The tree drank them in. The trunk thickened. It looked ancient. Vast. Alive in a way the world around it couldn't quite contain. The branches spread wider than the ruin. The roots drove deeper through the temple. The whole thing began to outgrow the shape it had worn before, as though billions upon billions had only been the beginning and now the rest of creation had joined in.

The tree ran through Cassian, and through Bathsheda, and through the line between them. Cassian felt every buried variation he had ever touched, every old spell, every lost branch of magic, every memory the world had cut loose and the tree had kept anyway.

The Crown understood then. It had feared the split the first time. This was worse.

Cassian looked up through the blazing branches, through the silver flood of worlds emptying themselves into the one moment that mattered.

He had thought before that he was time and Bathsheda was space.

That had been true. It had also been far too small. Together, they were the point where time and space agreed to become one thing again. The moment through which the tree could remember itself across every branch it had ever grown.

The light pouring through the slits intensified.

The Keepers had gone still. Even the wounded ones were staring. Even the Flamels, even Dumbledore, even Coriolanus, all of them caught under the impossible weight of the sight. The Crawlers had dropped low around the roots, black and white alike, every one of them turned toward the tree like hounds at the feet of a king returned.

The Crown roared and hurled everything it had left into the dark around it. The ruin shook. The temple screamed. Blackness exploded outward in a storm of force and broken stone and ancient cursework dragged up from the marrow of the earth.

Cassian held Bathsheda's hand tighter.

He laughed.

"For years, I kept asking why me," he said, staring at the thing on the temple. "Why a history teacher from a dull little world with no magic ended up here with a mind that won't forget and trouble turning up every time I think I've earned a quiet week."

The Crown's dark power kept hammering at the ruin. The tree held. The roots held. The endless flood of Patronuses kept pouring through the silver slits torn across the sky, through time, through worlds, through every place where something living had once loved enough to remember it.

Cassian's grin sharpened.

"Then I remembered."

Cassian looked up into the vast pale branches overhead, then back at it.

"The Valley didn't need another king," he said. "It didn't need some perfect heir with a proper title and a dramatic haircut. It needed someone who knew what to do with memory. Someone who wouldn't hoard it. Someone who'd pass it on."

His fingers tightened round Bathsheda's hand, and the light running through them both flared brighter.

"In my old life, history was my whole trade. Dead names. Buried truths. The things people in power would rather lose. I taught them. That's what I did. I stood in front of rooms full of bored children and tried to make the past live long enough for them to carry a bit of it away."

A fresh surge of dark force slammed across the temple. The roots shuddered. The branches answered with a wash of pale light so bright the broken stone gleamed wet-white for a heartbeat.

Cassian barely glanced at it.

"When I came here, the interface looked like a trick. A helpful bit of nonsense. Teach a spell, get stronger. Lovely. Convenient. Completely insane." His mouth twitched. "But it was never rewarding me. It was reminding me all this time.

"It made me teach because that's how magic survives," he said. "That's how memory survives. You don't lock it in a vault and call it sacred. You hand it over. You pass it on. Root to branch. Teacher to student. One mind to the next. The world forgot ancient magic, so the tree fed it back through the only shape I'd recognise. A lesson plan."

The Crown's mouth twisted. The gold under its skin flared with violent heat.

, it said.

Cassian shrugged.

"Yeah," he said. "And?"

The thing's stare darkened.

It wanted outrage. Wanted grief. Wanted the old wound of not being enough. Cassian had lived too long with old histories and older ghosts to hand it that for free.

He lifted his joined hand with Bathsheda's a fraction.

"You keep making the same mistake," he said. "You think being incomplete is weakness."

The light around them surged.

Bathsheda stepped in beside him, shoulder brushing his. Silver-white runes spun from her free hand and climbed into the air in long spirals, folding through the roots, through the branches, through the silver slits torn across reality.

"You were wrong about her too," he said.

The Crown's eyes snapped to Bathsheda.

She met that stare and didn't blink.

Its hatred sharpened into something uglier.

Fear.

Cassian saw it and smiled.

"That's why your lot spent centuries erasing names," he said. "You knew memory mattered. You knew forgetting weakened the light. You had the principle right, even if you were too rotten to understand the rest of it."

His voice dropped.

"You thought cutting names out of books would kill them. Sometimes it did. Sometimes it nearly worked. But magic remembered anyway. The tree remembered. The world remembered, in bits and pieces, in wards and creatures and old stone and lost spellwork and dreams people didn't know how to explain. And I remember."

The Crown struck at the nearest root with a blast of black force. The root held for a breath, then split. Two more punched up through the floor in its place and wrapped round the thing's legs. White Crawlers rushed in low. Night Crawlers came at it from behind. The Patronuses above the ruin wheeled and dived.

"You were already winning," he said to the Crown. "You'd got too good at cutting the past out of people. So the Valley cheated."

The Crown jerked as though the words themselves had hit it harder than anything they'd thrown so far.

Cassian laughed again, brighter this time.

"It reached outside the whole bloody system and grabbed a man who teaches for a living, a man who loves history too much to leave dead things buried properly, and shoved him into the one place you'd least enjoy him. Then it gave him a mind you couldn't scrub clean, and a trick that turns teaching into restoration."

He lifted his chin.

"That's why me."

The wind changed over the temple.

The branches overhead shone so brightly now they had begun to cast pale shapes across the ruin like moonlight through leaves.

The Crown looked up, then back at Cassian.

Its voice came jagged.

He turned his head and looked at Bathsheda properly. Smoke, blood, dust, silver runes, pale light, hair half loose from the fight, jaw set in that way he knew far too well by now. All the impossible years between Norway and now seemed to appear in her eyes. The cave. Greece. The fractures in time. The mark. The runes she had always somehow known. The worlds she could hold in her head without breaking.

"She's my better half."

The Crown tried to shake off the roots.

, it said.

Cassian's grin flashed.

"Oh, yes."

He stepped forward and the roots surged with him.

"For all your talk," he said, "you still don't understand the thing you're fighting."

The Crown's dark power rose in a wave. Cassian felt it build before it struck. Anger. Panic. Malice. The full ugly force of something ancient realising the world had slipped an inch beyond its reach.

It came at them.

Cassian and Bathsheda moved together.

His free hand cut down through the air. Hers lifted.

What came next was less like a spell and more like the world snapping back. The dark wave hit the roots, the runes, the slits, the tree, and all of it folded, bent, and broke apart. The blackness was taken apart. Some of it burned in the roots. Some of it vanished through widening seams of silver-blue. Some of it struck the tree and came back white.

The backlash drove straight into the Crown. It staggered. The gold cracks under its skin burst bright, then dimmed. The Crawlers hit it in the same heartbeat. White and black together. One to the chest. Two to the legs. Another to the back. Patronuses crashed into it from above.

The Crown roared. Cassian could hear Keepers behind him moving again, rallying, lifting wands, pulling themselves upright, old fear giving way to the sort of fury that only came once people realised they had not, in fact, lost yet.

The Crown thrashed against roots and claws and light.

The tree blazed above them.

And this time, when the darkness surged again, the whole world surged back.

By all means, save the praise for my funeral. It will look splendid beside the flowers and all that excellent timing.
