The dawn broke over Aetherion, burning away the lingering morning mist that shrouded the four corners of the fortress.
High on the balcony of *Barad-Glinn Nim*, King Arthur stood alongside Glorfindel and Arandhir, remapping troop movements along the *Echoriath-Sûl* defense line.
Northern Sector: Nordfall Post
Under a biting northern wind, Halbarad led his clan through Nordfall, moving like shadows among the slick stone crags.
Their sharp eyes scanned the hillsides to ensure no intruder went unnoticed.
Standing ready on the 30-meter-high stone wall designed by Erestor were 100 fully armored knights.
At the top of the tower, 40 archers stood with bows drawn, prepared to rain arrows down into the valley.
These forces were assigned by Arthur to Nordfall Post, joining Halbarad’s 200 Rangers and their families who resided here.
At the highest point of the post, five soldiers stood beside the *Beacon of Nordfall*, keeping the signal fire ready to alert the realm if Angmar should stir.
Arthur named them the Dirnhael-Nord – The Iron Watchers.
Eastern Border: Zhar-Gij Fortress
Far on the eastern border, where the threat of Trollshaws Orcs lurked most often, defense trenches fitted with forged Rivendell steel spikes were manned by the Gargor-Dun clan.
Led by Boran, 250 tough fighters grinned as they watched the narrow path beneath the cave.
After *Echoriath-Sûl* was built, Arthur sent Boran 70 additional troops to reinforce Zhar-Gij, including a cavalry unit.
On the rocky cliffs above, 50 human archers held crossfire angles.
Behind hidden black iron gates deep in the cave, 50 mounted cavalry waited.
Once the enemy fell into the three-way trench trap, the cavalry was set to flank and strike.
Arthur named them the Dagor-Gathol – The Blades of the Iron Chasm.
Southern Line: Riverguard Post
Along the roaring river border, diverted water filled the circular trenches.
150 knights equipped with long spears and steel shields formed a tight barricade along the wall, ready to repel waves of enemy wolf-cavalry.
50 archers waited behind the trench wall embrasures to provide close-range cover fire.
Outside the perimeter, 20 light cavalry continually patrolled the banks of the Hoarwell River to stop any stealth crossings.
Standing along the wet trenches fed by the swift Hoarwell was Branoc “The Dammer.” Wearing local forged iron armor scarred by battle, the border veteran stared coldly toward the southern plains.
To Branoc, the river was not just scenery—it was a weapon.
Branoc walked the wall, verifying every water trap and timber stake.
To him, Riverguard Post was a living dam designed to drown any southern Warg raid before it could reach the foot of Weather Hill.
A native of the Hoarwell Valley, Branoc was a veteran river guard commander who had led Southern Eriador’s buffer militia before joining Arthur’s forces.
Arthur entrusted him with 150 knights, 50 archers, and 20 cavalry.
Arthur named them the Echor-Duin – The Ring of the Hoarwell.
Western Sector: Chet-Gate Post
Unlike the other sectors, Chet-Gate Post buzzed with human activity.
100 knights under Lady Morwen’s command patrolled the western route, escorting supply convoys and securing passage for civilians.
Inside the teak and dressed-stone structures, 50 knights guarded the supply granaries and *Healing Wards*, where dozens of Aetherion healers mixed herbal remedies to treat the wounded.
Lady Morwen moved with calm authority as she supervised incoming supply wagons from the Bree route.
A descendant of the Dúnedain, she brought both firmness and poise to the humanitarian hub.
“Ensure the medical supplies from Rivendell go straight to the Healing Wards,” Morwen commanded her family guards.
“And double-check the grain in the stone granaries.
We fight hunger just as we fight Orcs.”
Under Morwen’s leadership, Chet-Gate became an impenetrable supply core.
Coordinating 200 knights to secure the trade lines while overseeing the healers, she served as a sanctuary for refugees and a iron wall to any enemy approaching from the west.
A minor Dúnedain noble from a line of Bree border wardens, Morwen possessed deep expertise in managing settlements and supply networks.
Seeing the Light in Arthur’s rule, she swore her allegiance.
Arthur entrusted the western post to her, recognizing that this position required trade and administrative expertise alongside military strength.
Her command included 200 knights, 50 archers, and 20 cavalry.
Arthur named them the Rinn-Anor – The Keepers of the Sunlit Gate
Central Guard: Barad-Glinn Nim
At the heart of the defense, beneath the golden glow of *Galad-Calyen*, 100 elite knights and main cavalry waited as the Quick Response Force—a mobile strike unit ready to deploy to any compromised post.
The sun rose high.
At the peak of *Cala-Tirith*, rune-carved ice crystals emitted a soft blue glow across the hills.
The defense structure of *Echoriath-Sûl* was fully organized, prepared to repel any threat.
Aetherion’s population had reached 5,000, with 2,200 battle-ready troops comprising knights, scouts, archers, and cavalry.
In less than seven months, Arthur had established a recognized realm.
For now, Lord Elrond remained his sole formal ally, recognizing Arthur’s vital role against the darkness.
A few weeks after the fires of *Echoriath-Sûl* were lit, King Arthur rode Rochgál along the Great East Road toward the eastern border.
His visit to *Zhar-Gij Fortress* was not to lead a battle, but to inspect the readiness of the *Dagor-Gathol* and examine the discoveries uncovered by workers in the underground tunnels of *Nogrod-dûm*.
Under the iron-plated walls of *Zhar-Gij*, Chieftain Boran and Kael greeted the King.
“Welcome back to the Eastern Fortress, Your Majesty,” Boran whispered, leading Arthur, Arandhir, and Elmir into a deep forge chamber recently cleared of ancient rubble.
Dust fell from the ceiling as the secret stone door of *Nogrod-dûm* lifted.
The ancient forge was quiet, illuminated by the warm silver light of *Glow-stone* crystals.
Arthur approached the main forge table and ran his fingers over a massive, cold metal map—a relic crafted by the Dúnedain and Khazad-dûm smiths.
“Remarkable…” Arandhir whispered, raising his torch.
It’s a complete topographical map of the underground tunnel network across northern Eriador.”
Boran stepped forward, tracing ancient *Cirth* runes until his finger stopped at an engraving of a mountain fortress in northern Trollshaws.
“By the ancestors…” Boran breathed.
“This is *Cameth Brin*.”
Arthur looked up.
“Cameth Brin?
The former crown fortress of Rhudaur?”
“Yes, Your Majesty,” Boran replied.
“It was once Rhudaur’s crown stronghold—a massive mountain fortress locking down the northern pass.
But since the fall of ancient Arnor, it has become a lair for hundreds of Gundabad Orcs and the remnants of Angmar.”
Elmir walked over from examining the *Lebethron* wood bows in the corner.
“A surface assault on Cameth Brin from the northern valley is suicide,” he noted, pointing to the fortress exterior on the map.
“The cliffs are sheer, and the winding trail is covered by archer posts and siege catapults.
Any attacking force would be cut down before reaching the outer gate.”
Arthur pressed a silver emblem shaped like the Star of Elendil set below the name *Cameth Brin*.
*CLICK.*
An ancient gear mechanism turned within the table.
A thin, ice-blue line of light trace through the metal plate—connecting their current position at *Zhar-Gij*, cutting through the subterranean roots of the Trollshaws, and ending directly beneath the main tower of *Cameth Brin*.
Arandhir stared at the glowing line in disbelief.
“A secret underground passage…
The ancient Dwarf and Dúnedain craftsmen built a direct subterranean shortcut straight into the heart of Cameth Brin!”
Arthur smiled faintly as his blade’s ice magic hummed in response to the map’s energy.
“Those who hold Cameth Brin believe its stone cliffs and catapults make them invincible.
They sleep on ruins they do not understand, unaware of the trap beneath their feet.”
Boran looked at Arthur with renewed respect.
“With this tunnel, Your Majesty, we can move our troops unseen by enemy scouts on the surface and strike from within.”
Arthur turned to his commanders.
“Gather fifty heavy shield knights and fifty archers.
Tonight, we bypass their front gates entirely.
We march through the shadows of the ancestors and reclaim Cameth Brin from below!”
“It shall be done, Your Majesty!” Arandhir saluted, as Boran and Elmir moved to assemble the strike force.
Arthur looked back at the glowing path on the metal map.
The route to Cameth Brin was open, and the drive to clear the northern lands of darkness had begun.
