The cottage had grown significantly since Ereinion's arrival. Kaelen had simply "nudged" the hallway, and a third bedroom had unfolded like a paper crane, complete with a window that looked out onto a perpetual sunrise in the Timeless Halls.
However, the domestic bliss of two Elven brothers practicing "Void-Tag" in the gardens was interrupted by a summons from the King. Oropher was not a man of many smiles, but today his face looked as though it had been carved from cold flint.
The Council of the Greenwood
They gathered in the subterranean throne room, where the air was thick with the scent of aged oak and anxiety.
"The Shadow in the South has a name," Oropher said, his voice echoing. "The Necromancer is but a mask. My scouts have seen the Black Speech carved into the trees of the Amon Lanc. It is the Spirit of Sauron, and he is gathering the shadows of the past."
Thranduil stepped forward, his matte-black ring humming against his skin. "Let him gather them, Father. We have the Silence."
"He does not come with Orcs alone this time," Oropher countered, gesturing to a map. "He has unearthed a Wurm of the North—a descendant of Glaurung, a creature of fire and greed. It approaches the borders of our forest, burning all in its path."
Kaelen, leaning against a pillar and eating a handful of enchanted blueberries, looked up. "A dragon? That's a bit cliché, isn't it? Very 'First Age' of him."
The Brothers' First Mission
Kaelen decided this was the perfect "group project" for his disciples. He didn't want to just erase the dragon; he wanted the boys to understand the relationship between Energy and the Absence of It.
"Alright, kids," Kaelen said, clapping his hands. "Thranduil, you're the Heat Sink. Ereinion, you're the Binding. I'll be the one making sure the collateral damage doesn't turn the forest into a charcoal briquette."
They found the dragon—a massive, copper-scaled beast named Ignis-Vex—at the edge of the Grey Mountains. It was breathing a torrent of flame that melted stone into glass.
"I will burn the stars from the sky!" the dragon roared, its voice a tectonic grind.
The Void-Combo
The Absorption: Thranduil stepped into the path of the dragon's fire. Instead of burning, he opened his arms. He created a Zero-Kelvin Aperture. The roaring flames didn't hit him; they were sucked into a pocket of absolute cold, their heat energy being converted into harmless, drifting snowflakes.
The Luminous Chain: As the dragon paused, confused by its disappearing fire, Ereinion leaped into the air. He didn't use a sword. He wove the "White Void" into shimmering, translucent chains of solidified starlight.
The Anchor: Ereinion wrapped the chains around the dragon's maw and wings. The chains didn't just hold the beast; they "vibrated" at a frequency that canceled out the dragon's internal heat.
The Mercy of the Void
The dragon crashed to the earth, shivering. It wasn't dead, but its fire had been stolen. It looked at the two Elven youths—one a Prince of the Woods, the other a scion of the High Elves—and saw the dark-robed Master standing behind them.
"You... you are not of this world," the dragon wheezed.
"I'm just a guy who likes his trees un-scorched," Kaelen said, walking up and tapping the dragon's snout. "Now, Ignis-Vex, you have two choices. I can send you to a dimension where there is no air to breathe and no gold to sleep on... or you can become the guardian of the North Pass. You'll keep the Orcs out, and in exchange, my boys here will feed you refined Void-energy. It tastes like spicy lightning."
The dragon, realizing it was outmatched by literal cosmic anomalies, bowed its massive head. "I... I choose the lightning."
A Brotherly Bond
As they walked back toward the Greenwood, the sun setting behind them, Ereinion leaned against Thranduil. The use of High-Void magic had left the young boy drained.
"You did well, little brother," Thranduil said, his voice uncharacteristically warm. He placed a hand on Ereinion's shoulder, a pulse of grounding gravity helping the boy find his feet.
"I felt the fire, Thranduil," Ereinion whispered. "It was so hot. But then I felt your cold. It was like... a shield."
"That's the secret," Kaelen added, walking between them. "Individually, you're powerful. Together? You're the equilibrium of the universe. One of you takes, the other gives. It's a pretty good system if you ask me."
They reached the cottage just as the first stars began to peek through the canopy. For the first time, Thranduil realized he didn't care about being a King or a legend. He just wanted to make sure his brother was safe and that Kaelen didn't accidentally teleport the teapot into the Fourth Dimension again.
Peace, it seemed, was the most powerful magic of all.
