When it cleared, a single chip of stone was spinning on the floor. Otherwise, the door was completely intact.

Lindon would have taken this moment to stop her from damaging the door any further—it was connected to some unknown script, and might bring the entire roof down on their heads if they interrupted the circle, not to mention its connection to Sacred Valley—but he happened to glance behind them.

Dreadbeasts scrambled all over each other as they clawed up the stairs, seeming to blend into a multi-headed mass of corrupted flesh.

Yerin braced her feet against the ground, her Goldsign drew back like a snake preparing to strike, and she gripped her sword in both hands. Colorless sword madra rippled around her until it was like he was looking at her through a cage of razors edge-on. As she gathered power, she focused on the door as though she meant to destroy it with the force of her stare.

Without giving himself too much room to think, he picked up his severed Remnant part and pointed it at the oncoming rush of beasts. His madra flowed down the weapon, trickling toward the binding.

“The big one,” Eithan shouted, but through his ringing ears Lindon heard it as a whisper. The man was standing now, but he was actually leaning his shoulder against one of the wider sections of wall, completely at his ease.

Lindon listened, adjusting his aim to point at the biggest of the dreadbeasts: a warped purple creature like a bear with heavily muscled arms. When he was close enough to see the bloodshot veins in the monster's arms, the dreadbeast hauled itself back on its hind legs. It looked as though it intended to come down on Lindon like an avalanche.

He stepped forward, thrusting the bright green stinger like a spear.

And just as he did, he activated the binding.

He used his weaker core, the Copper one, because it was just barely strong enough to fuel the weapon. The activation drew his core dry, and if that had been his only source of madra, he would have collapsed immediately.

But he pulled on his Iron core instantly, keeping his legs steady even as the binding activated.

Three hazy green duplicates, like less-real copies of the stinger, flickered into existence around his thrust. It was as though he drove four spears instead of one.

The bear fell on top of his weapon, but one of the Forged spears lodged in its hide. Another caught a Remnant in the head, and his actual spear drove even deeper into the bear's belly. The fourth strike missed, dissolving out of existence in a moment, but Lindon threw himself back as soon as his point bit home.

The venom only took an instant to scour the bear with agony, and it went berserk, flailing its paws and roaring so loudly that it hurt Lindon's ears even through the ringing. It turned in a circle, snapping its jaws as though trying to bite out the infection, and every other Remnant and dreadbeast fell upon it.

A hand caught him by the back of his robes and pulled him up the stairs just as a bloody, severed limb landed at Lindon's feet.

Eithan plucked at his own sleeve, indicating Lindon's clothes, and then shook his head.

Well, if Eithan wanted to pull him out of trouble to avoid getting blood on his borrowed outfit, Lindon wouldn't complain.

An explosion drummed his bones, and he spun with an arm thrown up over his eyes. Stone fragments pelted him through a cloud of billowing dust, and the remaining half of the door tipped over and slammed to the ground with the speed of a calving glacier.

Yerin's knees buckled as her technique faded, and she fell to the ground panting. Eithan and Lindon ran by her, each grabbing an arm without discussion, pulling her into the room beyond.

It was a broad, featureless hallway with an open doorway at the end. In the very center lay a circle of script.

The dreadbeasts wouldn't continue slaughtering each other for long, but Lindon spared a moment to admire the advanced script-circle on the floor. There were at least ten layers to the circle, lines of runes and sigils wrapping an empty space in the center.

Lindon and Eithan hurried around the edge, though Yerin regained her feet and ran on her own strength halfway through. Though the circle was much more likely to affect sacred beasts and Remnants, none of them were willing to run through the middle.

The outer circles brushed against the wall, so they were running on runes, and each step sent a little shock through the soles of Lindon's feet. His madra trembled as it cycled, as though drawn down to the floor.

He pushed on, and together the three of them reached the open doorway in seconds. There was, in fact, a door on the other side. This was a more ordinary type of door than the stone slabs before, made merely of dull gray metal and heavily caked with a series of script-circles. It had been left propped open, and judging by the dust sitting at its base, it had been that way for a long time.

Yerin and Lindon heaved together, and Lindon couldn't suppress a flash of pride that he was strong enough to help Yerin with something.

The heavy door slammed shut, its scripts glimmering for a moment as they drew power from the ambient aura. He and Yerin fell to the ground, gulping mouthfuls of the dusty air, and generally savoring their survival.

Eithan stood to one side, hands on his hips. “I have to say...this is fairly impressive.”

Lindon followed his gaze, taking in the space lit brightly by warm orange lanterns that were surely some kind of rune light. The lights were covered by paper screens to soften their glow, and it was a good thing; some of them shone too bright, uncomfortably bright, while others flickered off and on in a disquieting rhythm. They must have been powered by the vital aura taken in by the Ruins’ script, but either the script was broken, or it had been too long since they’d last come to life. The glow was uneven and left half the room bathed in irregular shadows.

The room looked more like a rich clan’s library than anything he’d expect to find in an ancient ruin, the colored tiles set with dusty carpets and beautifully carved tables. One of those tables held a collection of jade statuettes, one a cracked dragon with the head of a lion, the others a series of creatures stranger and more hideous. A glass-covered case displayed some tools of halfsilver and goldsteel, as well as more exotic materials that Lindon didn't recognize, but at least half of the spaces were empty.

Books sat open on stands carved for them, their curling pages painted with arcane diagrams and characters. They had browned from age, and Lindon was certain that if he so much as breathed on a corner, the paper would dissolve.

A row of silver hooks hung from the ceiling, which stood out as he couldn’t think of a purpose for them. They varied in size, but none of them held anything beyond empty air.

A long glaive made of Forged madra, with a blood-red shaft and a gleaming golden sword blade at the end, sat on a frame halfway up the wall. A circle of script surrounded it, sealing its power and preventing it from dissolving. Beneath the weapon, an image was painted directly on one wall: a circle, blank on one half, the other half complex and twisted with a network of lines.

Lindon stared at the pieces of the room for too long before they fit together into a whole.

This was a Soulsmith's foundry.

When he realized that, he shot to his feet and dashed to a nearby table, rummaging through it. He found nothing likely, despite pulling a few drawers open, so he slid to the next one, frantically shuffling through a pile of sealed ebony scrolls with scripts worked in gold filigree on their cases.

Yerin stepped up beside him, giving him a curious glance. “Looking for the spear?”
