The room is secure, but you are behind a sealed door. However, Aele notices that the stabilization has revealed a series of recessed handholds leading into a dark aperture at the very top of the basalt silo.

"The resonance is gone," Aele says, tucking the silver tube into his belt. "But we've kicked a hornet's nest. The Cabal will be swarming the Hall of Records. We can't go back the way we came."

It has been a few hours since the battle. During that time the heroes have eaten, drank, even napped some: it's surprising how well people can sleep even in uncomfortable surroundings when they're physically worn out. And our heroers are, while not exhausted, tired. They've had two big melees today.

"What's the nature of the loot?" Cabe asks.

Aele taps the scroll tube, indicating its contents. "This is a Cylindrical Alignment Key, written in High Thothian, that functions as a "Map of Resonance."

"That doesn't clear things up for me," Thistle adds, then returns to knawing on hard-tack.

Aele elucidates, "While held, I can detect the direction of the next unstable Cylinder within Arden Vul. It also contains the ritual 'Seal of the Archivist,' which can be used once to permanently lock a door against any non-divine entry.

"You're shitting me," Dorn says, sitting up.

"I shit you not" Aele returns, equably. "And in this vial is an incredibly rare alchemical substance. If consumed, one can act Hasted for 1 hour, but without the aging side effects. Alternatively, it can be poured onto a broken mechanical or magical object (like a spent wand) to "rewind" its state, restoring 1d6 charges."

All three of his fellows stare blankly at Aele. "Oh," he says, "of course: I should explain that Haste was an example of a form of magic from the Old Archontean Era. A spell. Someone is Hasted when the right magical forces are called into action — such as by consuming the contents of this vial."

Thistle nods, understanding. "Picture Dorn, except doing everything twice as fast during a combat."

Cabe whistles appreciatively and Dorn grins.

"Indeed," says Aele, and he leans over and gives Dorn the vial. "Save it for a special occasion."

"Not a problem," the big fighter replies. "I'm sure we'll have an Oh Shit moment one of these days."

"You mean we haven't had two of those today already?" Thistle says, grinning.

"So I take it there are other Cylinders in Arden Vul that need to be stabilized?"

"I'm not sure," Aele admits. "I wonder if the Sovereign would know?"

Dorn picks up the Violet Glass Jar, holding it toward the sapphire light of the Cylinder. He studies the way the violet mist inside swirls in response to the movement of his hands. As a seasoned warrior and a 5th-level Thief, he has a sharp eye for the practical value of "weird" dungeon salvage.

Dorn grunts, "If we find someone who can crack it open without blowing us to the hells, the glass itself is masterwork. But the energy inside? That’s the real prize. I’d say we don't let it go for less than 175 gp."

Aele consults the Map of Resonance while Dorn and Thistle examine the first few feet of the climb up the vertical shaft. Cabe walks over to look over Aele's shoulder at the map. "What Resonances does the map indicate? Are they sources of magical energy within Arden Vul, or more mundane power sources, or what?"

Aele carefully unfurls the Silver Scroll. As he does, the ink—which previously appeared as static, geometric patterns—begins to ripple and flow across the parchment, reacting to the Heart-Seed Scarab's proximity.

The map does not show physical hallways or tunnels; instead, it displays a series of glowing nodes connected by faint, pulsing ley lines that mirror the internal "nervous system" of the mountain.

Aele points to a cluster of icons as Cabe leans in. "It tracks Harmonic Stability, Cabe. The Thothian Empire didn't just build these as power sources; they were anchors for the reality of the mountain itself." Aele points out to Cabe on the map, "See here, this bright and steady sapphire light? That's the Fourth Cylinder, where we are right now."

Cabe studies the map. "What are these flickering points?" he asks.

"Those," Aele explains, warming to his subject, "are active points of instability. I don't know if they just started malfunctioning because of insufficient maintenance, or if perhaps this cult of the Violet Eye — if we can call it a cult — may be corruping cylinders are purpose."

"And these tiny points that are barely visible?"

"Most likely those are living energies, like the biomechanicals we just fought. Someone is building these and fueling them with corrupted energies from the misaligned cylinders. Or — Thoth forbid — the biomechanicals may have learned how to replicate themselves."

Dorn and Thistle join them for the last of the map discussion. Thistle says, "So, if I understand correctly, the Cylinders power lights, and lifts, and other mechanical things in Arden Vul, but also they anchor the mountain itself, and help prevent some of its more dangerous energies and inhabitants from ... leaking out into the rest of Issenda."

Aele turns to regard his pupil, "Thistle, I do believe your brain is doing one of those things again — pulling up information that is real, even if difficult to parse."

Dorn says, "Looks like it's safe for us to climb up the access chute. Are we ready?"

"Ah, yes of course!" Aele says, rolling up the map and stowing it. He turns to Cabe. "Did you notice? There's a major instability on Level 5 right now. What we might term a Resonance Failure. If the Cabal stabilizes their hold there, they could potentially reverse the flow of energy and turn this very room we're standing in into a vacuum."

With the bronze portal already physically locked, Aele recognizes the need for a more permanent, metaphysical barrier. He moves to the threshold, the Heart-Seed Scarab glowing with a rhythmic, emerald pulse that seems to synchronize with the sapphire light of the stabilized Cylinder.

"Before we leave," Aele says, "let's ensure our labors here have not been in vain." Aele unfurls the Silver Scroll and begins the Litany of Seclusion. His voice, normally steady, takes on a resonant, metallic quality that vibrates through the basalt floor.

Tracing the Boundary: Aele walks the perimeter of the circular bronze door. He does not touch the metal; instead, he traces the frame with the edge of the silver scroll. A trail of fine, glowing silver dust follows the scroll's path, hanging in the air like a frozen spiderweb.

The Invocation: "By the Ibis and the Scale," Aele intones, his eyes fixed on the geometry of the portal. "That which is ordered shall remain silent. That which is recorded shall remain secret. Let the weight of Ma'at sit upon this threshold, unmoving until the stars themselves reset!"

As he finishes the prayer, he slams the silver scroll tube against the center of the door. The silver dust "snaps" inward, sinking into the bronze. The door groans once, and a faint, shimmering field of force—like a heat haze—ripples across the surface.

Thistle's eyes are big as saucers.

"The ritual is complete. The Fourth Cylinder is now a sealed sanctuary," Aele pronounces with satisfaction. The door is now magically barred. It cannot be picked, forced, or bypassed by anything short of a high-level Dispel Magic or the specific Master Key of the Archivist.

"Oh, I understand," Thistle says. "The Cabal’s violet energy can no longer 'leakl into this room. The Cylinder is safe from further tampering for the foreseeable future."

"Just so," Aele agrees.

"Nice work, everyone. Let's climb!" says Dorn.

With the room sealed behind them by the Seal of the Archivist, the party begins the climb.

Dorn leads the way. His 18 Strength makes the vertical climb look effortless. He moves with a predator's grace, his eyes scanning the bronze rungs for any sign of Thothian "security" measures or structural fatigue.

Thistle follows. Strengthened by his recent advancement and his new 13 Constitution, he keeps pace better than he ever has before, his breathing steady despite the verticality.

Cabe and Aele bring up the rear. Aele hitches his robes, the Heart-Seed Scarab glowing faintly against his chest, illuminating the rungs for those below.

The shaft is perfectly circular, carved with a precision that defies the age of the ruin. As the heroes climb, the "parchment and ozone" scent grows stronger. After approximately sixty feet of vertical climbing, the air pressure shifts and they feel a steady, cool draft pulling upward.

Dorn reaches a point where the rungs end. He hauls himself up onto a wide, flat ledge. He reaches down a gloved hand to pull Thistle, then the others, onto the platform.

The heroes find themselves in a massive, horizontal rectangular corridor made of dull gray stone. Huge, unmoving bronze fan blades, each ten feet long, are set into the walls at intervals.

To the east, the corridor continues into darkness, the floor covered in a thick layer of grey dust, while to the west can be seen a faint, flickering violet light reflecting off the walls—the unmistakable sign of Cabal activity or a rogue energy source. Directly ahead, a heavy iron grate has been rusted through, leading into what looks like a series of smaller crawlspaces.

"We're behind the walls now," Cabe whispers, checking his bowstring. "In the spaces the Archivists didn't want the public to see."

Cabe sees Dorn wince and realizes that the big fighter is still considerably wounded. Cabe initiates what we'll term a 'Cabe Health Adjustment'. As Cabe’s blood-bond pulses with a deep crimson light, Dorn’s bruises fade while Cabe winces, a pale exhaustion crossing his face. Because Cabe is currently at full health, his Regeneration will begin ticking at the start of the next combat round to refill that deficit. Dorn has regained 5 hit points.

"Give me a minute and I'll hit it another lick," Cabe tells Dorn.

"Good, do so, because according to the Map of Resonance," Aele announces, "there are Cabal forces to the west of our position."

As Cabe initiates the Cabe Health Adjustment, he reaches out and grips Dorn’s shoulder. A visible ripple of crimson energy transfers from the specialist to the fighter. Dorn’s posture straightens as the last of his deep fatigue vanishes, while Cabe staggers, his skin paling as the tax on his life force takes hold.Cabe has adjusted another 10 hit points, healing Dorn and bracing himself, hands on knees as he takes the hit and his body begins to regenerate the damage.

There is a 1-in-6 chance a Cabal Crawler discovers the heroes while Cabe is regenerating. The dice favor the Brothers! The 14 rounds pass in a tense, dusty silence. The only sound is the rhythmic thrum-thrum of the Resonance Relay and the faint, wet sound of Cabe’s biology accelerating its repair.

With the party mostly mended and the ventilation plenum quiet, Dorn and Cabe slide through the shadows of the massive bronze fan blades, closing the distance to the Resonance Relay.

Dorn moves with the fleet grace of a veteran, while Cabe’s footsteps are silent, his focus entirely on the clicking brass legs of the constructs.

Because the Cabal Crawlers are sated and distracted by the violet energy, the heroes gain a Surprise Round. Aele and Thistle hang back near the rust-eaten iron grate, ready to provide support if the front line falters.

Dorn lunges from the dark, Swift trailing a line of blue-white light. He uses his Great Strike (+1 to-hit and damage) to aim for the central joint where the Crawler’s brass thorax meets its legs.

Attack Roll: 17 
+ 1 (Great Strike) 
+ 2 (Surprise) 
+ 2 (Swift) 
= 22 (Hit!)
Damage: 11
+ 2 (Swift) 
= 13 damage

The blade shears through two brass legs, sending a spray of violet sparks across the floor. The Crawler screeches—a sound like metal on a whetstone. Combined with Cabe's 8 damage, the first Crawler didn't just collapse—it was practically cleaved in half before its gears could even register the threat.

The remaining Crawler lunges at the man who just destroyed its twin, but its claws skitter harmless across Dorn's shield. Its violet eye flashes with frustration. Above, the Resonance Relay is reaching a fever pitch. The "red alert" light is no longer flickering—it’s a steady, blinding crimson glow, and a low-frequency hum is making the heroes' teeth ache.

"It's about to bridge!" Aele shouts, his hand tightening on the Heart-Seed Scarab. "If that pulse hits the next relay, the whole sector will wake up!"

Dorn deals another 13 damage to the remaining Crawler, putting it out of commission. When he turns around, he sees that Cabe and Thistle have the Resonance Relay, which Aele studies with them. The relay appears to be dying, losing power.

The Path Forward The dust in the plenum begins to settle. The immediate silence is heavy. Aele motions for the group to gather closer to the rust-eaten iron grate leading toward the smaller crawlspaces.

"We cannot stay here," Aele whispers. "The destruction of a Relay is like a missing tooth in the mountain's mouth. The Overseers will feel the gap in the resonance soon enough."

Dorn wipes a smear of violet oil from his blade. "Which way, Aele? We follow the dust East, or do we squeeze through these grates and try to find a way to Level 5?"
