In The Great Tree

In The Great Tree
The air grew heavy, thick with the scent of ozone and crushed pine. The silver veil of the portal began to crackle with arcs of lightning. 
Not yet. 
There was something she was supposed to do.
She tore her gaze away from the chaotic growth of the portal and looked down at the massive stone altar that sat directly in front of the ghost marker. The altar was designed with a series of deep, geometric channels. The channels were dry. The water was pooled uselessly at the base of the altar, spilling across the floor into the basin she’d washed up in.
Isorai knelt by the altar, wiping away a thick layer of dust and encroaching moss from the smooth stone surface. She traced the geometric grooves with her fingers, searching for the core arrays.
Then, she saw it.
Near the central junction where the primary ley-lines intersected, the delicate, silver-inlaid runes had been gouged, deliberately splintering the flow of the spell.
Isorai’s breath hitched as she examined the angle and depth of the cuts. The precision of the sabotage spoke volumes. Whoever had done this knew exactly which rune to destroy to shut down the entire system without destroying the structure itself. They wanted to isolate this place. 
It had t have been another Moongrove…. Most likely her mother.
To protect the heart of their people, her mother would have thought nothing of sacrificing a temple or three. No one of the line would, but she had to get it open to make sure no one would ever have to do this again.
Kneeling before the defaced altar, Isorai bit into the meat of her thumb until she tasted copper and the bright, metallic tang of blood welled up. Using her thumb as a brush, she pressed her hand to the cold stone and began the grueling process of resetting the spellwork.
She closed her eyes, channeling her focus away from her exhausted, aching muscles and deep into the near empty core of her remaining magical reserve. She envisioned the broken circuit. She felt the stagnation of the water below, the frantic, blocked energy of the guardian trees above, and the silent, watchful presence of the ghost marker behind her.
Carefully, she began to draw. Her blood filled the jagged gouges, bridging the gap where the silver had been scraped away. She recreated the anchoring runes, her fingers tracing the familiar geometric arcs of the Southern Council’s oldest binding seals.
As she painted the final line, connecting the broken arc back to the primary channel, she shouted a single word of command in the ancient tongue.
For a terrifying second, nothing happened. The blood remained dark and wet against the black stone.
Then, the altar shuddered.
The blood began to glow with a brilliant, luminous gold light, sinking deep into the porous stone and replacing the missing silver. A low, resonant hum vibrated through the floorboards. From the basin below, the sound of rushing water suddenly intensified.
With a soft, melodic splash, the cold, purifying water surged upward, rising through the intake valves and spilling perfectly into the newly restored channels of the altar. The water swirled through the geometric patterns, glowing with a serene light, before spilling over the far edge of the altar in a beautiful, controlled waterfall that drained safely back down toward the underworld.
Above her, the violent, crackling lightning around the portal vanished.
The gnarled roots stopped their aggressive expansion, settling peacefully into the stone floor, their bark darkening into a healthy, vibrant brown. The luminescent leaves of the guardian trees rustled softly, shedding a gentle, comforting green glow over the chamber. The silver veil of the portal stabilized, smoothing out into a perfect, mirror-like surface that radiated a welcoming warmth.
She stepped forward and stumbled out of the receiving archway, her knees giving out immediately as she collapsed onto a bed of soft, thick moss. The air here was entirely different from the heavy, damp atmosphere of the hidden temple. It was warm, perfumed with the rich scents of blooming night-flora, ancient loam, and the unmistakable, deep hum of the Grove’s heart.
She lay perfectly still for a moment, her face pressed into the cool moss, listening.
There were no alarms. No sounds of battle. No screaming of wind or the terrifying roar of the vroth rising. 
But it was happening and the longer she lay down the closer to annihilation they or it could be.
Slowly, she pushed herself up, her wet clothes shedding a steady stream of drops into the thirsty moss below.
She was in the boughs of the Great Tree. Massive branches loomed overhead, their branches woven together so tightly that they formed a living ceiling, filtering the moonlight into a soft, emerald-tinted glow. Giant, pale mushrooms grew along the bases of the limbs, providing a natural, faint illumination.
The absolute silence was deeply unsettling.
Isorai forced her aching body up and began to walk toward the central pavilion.
Every step felt like a monumental effort. Her boots were ruined, her tunic was torn and stained with a mixture of underworld silt, her own blood, and the iridescent residue of the portal magic. 
As she walked the grand stone lamps that lined the pathways were dark, their crystal housings shattered. In some places, the manicured gardens were trampled, the delicate flora crushed into the dirt by heavy, armored boots. There were no signs of a massive, bloody struggle, but there were unmistakable signs of a hurried, chaotic evacuation. Or a purge.
An attack had emptied the boughs of the Great Tree. She rounded a massive curve in the path, where the trees parted to reveal the grand plaza that led to the the altar of the Grove, a massive, circular structure of white marble where the elders gathered to observe ascensions. At least, they had once. 
She kept walking, her stomach churning as she walked on. 
Tall, jagged iron spikes, stuck out of the ground,. As she grew closer, she swooned from the psychic agony coming from the spikes. 
They weren’t spikes. 
They were spears. 
Heavy, black chains were wrapped tightly around them all binding them there and locking them in place. 
This was malicious, chaining a Moongrove’s spear like this. It was like chaining their souls. 
But who could have done this… if not another Moongrove?
Before she could process the implications, the sound of approaching footsteps echoed. They were heavy, synchronized, and metallic: the unmistakable cadence of heavily armored soldiers.
Here? In the Grove?
“She retreated to the Inner Sanctum a few hours ago. I think she’s still trying to get into the archive,” a young, male voice said. “But there’s soldier everywhere…. S-She never said how ba-bad it would be. And then she had this massive iron spike. Sh-She— She had them all…”
“It’s okay,” a woman said. She sounded maternal. “Just breathe. I’m going to get you somewhere safe.”
“What about you?”
“I have business to take care of, but I’ll be right behind you.”
Who was talking, and where were they headed? Could she help?
