Tim Pratt - Venom in Her Veins

“Which way?” Krailash said when the path at the end of the shaft dead-ended at a corridor running off to the left and right.

“Left,” the derro said. “Nothing the other way but pit traps and grell.”

Krailash had spent many years in dungeons during his youth, and he had no fondness for either of those things, assuming they really waited down that tunnel. He wished the psion-what was her name? — were here. Her kind could sense a lie. “If you’re not telling the truth, the rest of your life will be very short, but it will also be so unpleasant that you’ll wish it was even shorter .”

The derro shrugged and inclined its head to the left. Krailash nodded. “Men, two of you in front of me. Alaia, if you’d stay behind me. And two more men to cover the rear.”

They walked in silence, Krailash’s head brushing the low ceiling. Eventually the derro stopped, nodding to a patch of porous orange stone. “Wormrock. Practically alive. Grows fast, so we use it to hide our passages. We just need to dig through here.”

Krailash frowned. “If you brought Julen this way, then surely it hasn’t had time to grow back yet.”

The derro tittered. “ He went right. Fell in a pit trap. That’s how they caught him. But this is the fastest way to the pens. We might even beat him there. Wouldn’t that be nice for you? Get there before they decide whether to eat him or make him a mushroom farmer or give him to the Slime King as a toy?”

Krailash gestured. “Cayley, Fallon, Morris, Hemingwood-break through this rock.” The guards, all seasoned men who’d served with Krailash for years, obligingly stepped forward and hacked with their hand axes. The wormrock crumbled easily, leaving behind negligible piles of dust, and it wasn’t long before they’d chopped their way through into another tunnel, that one vast, easily seventy feet wide, roughly-gouged and streaked with dark black and red patches that Krailash wanted to believe was some cave lichen, but which looked much more like ancient dried blood. “What is this place?” Krailash said.

“We call it the Causeway,” the slaver said, and tittered. “It’s the cause of no end of trouble. Some great monster crawled through here, clawing its way through the rock, in the long long ago. Left a path so wide and broad and clear that fools think it’s safe.”

Another titter, and Krailash cuffed him on the side of the head.

“Just lead.”

They followed the Causeway for more than an hour, the passage angled steeply down all the while. The derro muttered about all the things that might kill them, and no number of cuffs to the ear or hissed orders could make it shut up for long. The sense of impending danger was so intense that Krailash began wishing something would attack them, just to break the tension. Spending too much time in the dark could make one go mad, Krailash thought. No wonder the derro were insane.

“Welcome to the depths,” the slaver said at one point, and giggled. “No more simple Upperdark for you. No basements or mineshafts or quarries or pitiful surface scratchings in the earth, no, no. We’re two miles down, at least, and some of the things that live here think the sun and stars are just stories told to frighten children. Can you feel the wonderful weight of all that stone above us?”

“Shut up,” Krailash growled.

Finally, after another long period of silent trudging and tense watchfulness, their prisoner pointed to a dark mouth of stone off to one side. “There. That’s the passageway.”

The hole was narrow enough that Krailash wasn’t sure he’d make it through without a pickaxe to widen the way, but by twisting his shoulders, he shoved his body through. He dragged the derro in after him by its chain, and pushed it to the front. The others filed in and gaped around. They were in a cavern obviously carved over centuries by long-gone flowing water. Bulging crystals emerged from the walls, some of them glowing with faint purplish light, and towering stalagmites rose from the floor. The party continued into the cavern for a while, and the slaver got more and more agitated as they went. “This way, this way!” The derro bounced on its heels, so eager to move forward that Krailash immediately feared an ambush, and tugged its chain, drawing it up short.

“There’s something strange about this one,” Alaia said, squinting at one of the stalagmites, far larger than the others they’d passed. “I don’t think it’s made of stone. It seems to be … How strange. Helmets, and rusting swords, and a cart wheel, and the belly of a wood stove, held together with something sticky, like sap. Something made this.”

A distant noise impinged on Krailash’s consciousness. The Underdark was not a very quiet place, really: the echo of footsteps reverberated hugely; there were rumbles of distant earthquakes or, more likely, creatures burrowing all around them; and the constant trickle and drip and roar of subterranean water was a rising and falling background hum. But the new sound was not like any of those: it was a buzz , like a swarm of small insects close by your head.

Or a swarm of very large insects rather farther away.

He jerked the tittering derro’s chain. “What is this place?”

“You’ll know soon enough,” it said. “It’s a swordwing nest.”

Krailash stared at the hideous prisoner. He’d never encountered a swordwing, but he’d once adventured with a dwarf named Halbert Hammerfist who had. The dwarf liked to boast of how his party had broken through the wall of a dungeon into a cavern and found it alive with hideous flying monsters. They’d slain the creatures, and found their nest, which was filled with treasures and relics looted from a thousand murders. Upon further questioning, the dwarf had gloomily admitted that everyone else in his party had died within moments of the swordwings’ initial attack, and that he himself had survived only by expending a wish he’d been granted by a djinn. Hammerfist had carried an axe with a viciously serrated blade he’d fashioned from the arm of one of the swordwings, and that blade had lent credence to his otherwise improbable description of the monsters. Human-sized insects with four immense wings each, bodies covered in chitinous armor of razored spikes, with limbs that were living weapons, capable of slicing a man in two right through his armor. Darting so fast in flight that they seemed to teleport-it was possible they did teleport-and attacking in coordinated teams, they were death on the wing, and the dwarf reckoned they were the most dangerous things he’d ever encountered in a lifetime of adventuring aboveground and below.

“Swordwings,” Krailash said, and shook the derro. “Are you mad? We’ll all die! You too!”

“Yes,” the derro said placidly. “But I’ll die down here in the dark where I’m supposed to, not under some horrible sun.”

Krailash lifted his head as the sound of buzzing intensified, and started to shout a retreat, but then the derro looped its leash-chain around Krailash’s throat and began trying to strangle him to death.

What struck Julen the most profoundly was how dark the Underdark wasn’t . Oh, at first it had been all shadow and mineshafts and abyssal depths, and his captors didn’t bother with torches or sunrods, but in the past hour he’d counted at least four separate kinds of natural illumination: glowing fungus; crystals lit with an inner light; patches of shining cave wall that must be the glowstone he’d read about; and disgusting, many-legged insects, big as mice, that swarmed over especially damp portions of the caverns and glowed like fireflies, but larger. As they descended ever deeper, Julen began to think the areas of absolute darkness were rarer than those in which there was some form of light. True, none of those lights were bright enough to read by, or even to tie your bootlaces by, but when deprived of light for too long, the human eye could make great use of even the faintest illumination, and with effort could turn a candle into a lantern and a lantern into a sun.
