"I hope you know where you're going," said Nyvara, as the three of them trod the branching passageways beneath the city.
"I know the direction," replied Zarenis, "I can feel it. This thing,,, the Presence, whatever you want to call it... it shows me images sometimes, but mostly I just sense the way I have to go. All I have to do is work out the details."
"That doesn't sound very reassuring," complained the sorceress, "how do we know it isn't lying to you?"
"It has no reason to. It wants to be released, and my demonic ancestry is the strongest link it has to this world." She didn't add that the Presence had already shown her that it had been responsible for her own birth, through a lesser demon. Since she had touched the censer, it could send her visions while she was awake, and she had experienced first hand its ability to manipulate the infernal taint in her blood, tying them together.
At least, she had now been able to gain some measure of control over the new powers in her blood. She was able to suppress all the transformations it wanted to make in her body, restoring her eyes and horns to their usual forms, and now looked as human as any tiefling should do, not like the hideous half-demon she had been at risk of becoming.
In truth, she did not know how far she could really trust the entity, but there was little doubt that following its demands was the best course of action for the time being. It said that it would bring her power, make her its primary voice in the physical world, once it was released from its prison. Given the trouble it had gone to in order to create her, that seemed at least plausible. It didn't seem to be able to act without some sort of intermediary, and it was unlikely that a better candidate existed anywhere near Haredil.
So now she, Nyvara, and the sorceress' bodyguard, Rolgor, where stalking through the tunnels under the city, looking for the key that could release the Presence. The visions it had sent of where exactly the key was, and how it was guarded, had been vague; evidently, the Presence had difficulty seeing into that part of the tunnel system. But she knew enough to be able to get there, and enough that it was obvious she would need assistance in doing so. Nyvara, who was simply mercenary, was a far better choice for that assistance than anyone Amloth could have provided, for it had also become clear that, in the long run, the drow would be her greatest rival if she wished to truly act as the Presence's chief representative on Earth.
"I can't believe," continued Nyvara, "that there are people who do this sort of thing for a living. Is it something about penetrating deep passages? This place is dusty and grimy, and if I wasn't holding a magical light, we wouldn't even be able to see anything."
"We're not adventurers," Zarenis reminded her, "we're here to get one thing, not to explore. In and out, as quickly as possible, that's the idea."
"Well, I don't see any treasure to steal, anyway, if that's what they're in it for. What kind of idiot leaves piles of gold coins lying about in a catacomb, anyway? I'm beginning to wonder whether there's anything down here at all, except dirt, smells, and scalding water from the springs."
They turned a corner. "There's that," said Zarenis.
In front of them, the corridor was choked with a vast profusion of mutated plants, springing out of the water channel that filled much of its base. The plants were greyish and blotched, unnaturally growing down here in the perfect darkness. There were tendrils that visibly writhed as they watched and buds that looked more like vicious mouths.
"Can't hack through that," said Rolgor, speaking for the first time since they had descended into the depths, "too much bad."
"A spell won't work, either," added Nyvara, "anything I could use against it would have to be strong to risk bringing the roof down. I hope this isn't your only way in."
"This is a tool of the Presence," said Zarenis, confidently, "nothing more. A sign of the encroachment of its world into ours."
"And that helps us how?"
"Because it knows its own." She strode forward, until she was right next to the edge of the vegetable barrier. The creepers waved about uncertainly, reaching for one her moment, then rearing away.
Zarenis closed her eyes, relaxing her hold on the blood that raged deep within her, letting a little more of the Presence out through her. It was less shocking than the previous times it had happened, partly because she knew what was coming, and partly because she had the transformation more under her control. Heat rose within her, and she felt her horns and fingernails lengthen. Her ankles twisted, and she felt a sharp pain above her buttocks as a growing tail pressed against her clothing.
She heard Nyvara take a sharp breath, not quite managing to hide her distaste at the tiefling's shape-shifting. When Zarenis opened her eyes, she knew that they were blood-red, and that even her skin was tinged with a reddish-purple hue. In front of her, the plants reared back, pressing themselves hard against the walls of the tunnel, opening a narrow passage between their bent stalks. It went about twenty feet into the morass, before more plants closed off any view of what lay beyond.
"I would follow very closely behind me, if I were you," she told the others.
Rolgor looked to his mistress, more uneasy about the plants than about Zarenis' demonic appearance. The sorceress looked uncertain, but, clenching her fists, stepped forward to stand immediately behind the tiefling, and then follow as she walked into the cleared passageway. The half-orc immediately followed her, although it was clear that he was gripping the haft of the axe they had found him very tightly indeed.
The plants continued to squirm, rustling against the stone walls, but, as they walked forward, those at the far end of the vegetable tunnel began to open up, revealing yet more beyond.
By the time they were twenty feet in, the mutant plants began to close behind them again, sealing off their only escape. Nyvara and Rolgor absolutely needed her now, if they were ever to escape, for Zarenis knew that there was no route to the surface beyond this point -- she would hardly have come this way if there had been. They were trapped in here, with her.
The same thought had obviously occurred to both of them, and even the muscular half-orc flinched now as tendrils began to reach out for him, stopping less than an inch from his skin. They kept very close to her after that, their bodies almost touching as they continued to walk ahead.
In fact, while it must have seemed like an eternity to the other two, Zarenis judged that they had gone only another ten feet or so before the plants continuing to open up ahead showed, not more of their own kind, but the blackness of an open corridor. Not long after that, they had passed through, and were standing on the other side, as the horrible mutated barrier closed up behind them.
The passage they were in looked no different from that on the other side, with a deep conduit for the hot spring water occupying most of its width, and a narrow walkway along one side. Zarenis paused for a moment, to allow her body to resume its normal appearance. Although she sometimes needed to allow her new demonic form to come to the surface, it was not an experience she enjoyed, and the sooner she was back in her own flesh, the better she felt.
A sudden vision sprang to her mind of a dry side passage. She knew she would find it up ahead, and that that was where she had to head next. She also felt a sense of foreboding, her senses warning her to the fact that here, beyond the protective barrier, the Presence held more sway than it did elsewhere in the mortal world, and that anything could have been attracted here by its otherworldly nature.
"I'm not sure what's here," she told the others, "but there's no reason to assume anything else will behave as quietly as those plants just did. So we will have to be careful."
"There bad smell," said Rolgor.
"This whole place is dank," pointed out Nyvara, "you'll have to get used to it."
"No, real bad smell." The half-orc hefted his axe, and moved to stand in front of the two women.
Something scuttled out of the darkness ahead, the magical light from Nyvara's wand catching on a glistening green flank. The thing was running along the side of the tunnel, not along the floor, and it was headed straight for Rolgor. His axe whirred through the air and hit the thing with a heavy thudding sound, making it emit a high-pitched screech and back off. They could all smell it now, an unpleasant rotting odour that perhaps gave some clue as to what the thing fed on.
Now that it had paused it was easier to see what it was... or at least, what it looked like, for none of the three could recall having seen anything quite like it before. It was about ten feet long, with a body that loosely resembled a caterpillar, or possibly some kind of maggot. An array of long tentacles sprouted from its head -- one of them severed and oozing pale yellow fluid. Dark, insectile eyes glittered above a wide maw filled with dagger-like teeth and a pair of bone-crushing mandibles.
The thing hissed and lunged forward again, tentacles flying around it like a shield. Rolgor swung his axe, but there were too many tentacles and one of them slapped him across the legs, spattering transparent slime as it did so. The big half-orc let out a grunt of surprise as one leg went numb, collapsing beneath him to pitch him onto the floor. Another tentacle swung by just inches above his head, but then the monster scuttled forward across the wall, now poised directly above him, tentacles waving.
Nyvara cast a spell, a bright blue spark of energy that momentarily obscured the light from her wand. It struck the creature, making it hiss in fury as it retreated a couple of feet up the wall. With a shout of rage, Rolgor reared up on his remaining good leg, swinging the axe one-handed, powerful muscles rippling beneath his tunic. The axe bit into the creature's side, spraying yellow fluid onto the blade, and the thing stumbled, half falling off the wall to crash down beside him.
Before it could recover, the half-orc gripped his axe in both hands, half-leaning against the wall to support himself, and rained down blow after blow on the thing's head until long after it had stopped moving.
He remained there, panting with exertion for a while. "Leg numb," he said, after a while, "can't move it. I not hurt... but leg bad."
"Some sort of paralysing contact poison," commented Nyvara, "whatever that is, it must secrete the stuff."
"If we find an adventurer," said Zarenis, "we can ask them what the thing is. But can you reverse the effects?"
The sorceress nodded, "it should be simple enough, with a neutralising balm. But I hope you aren't expecting the sort of powerful healing magic that can put limbs back. I'm not a priest, and there could be something worse out there."
"There's an area up ahead that's safe," Zarenis told her, "we just have to get there quickly."
Nyvara's balm was as good as she has said, and soon the three of them were headed down the tunnel again, moving a little quicker this time. The side tunnel was, as the tiefling had thought, not far ahead, and, unlike the main passage, it was entirely dry, without any conduit along the floor. It was evidently a later addition to the system, not part of the channels for the hot spring water, although its original purpose was far from clear.
