The Gauntlet
Once they had finished eating, they packed up their things, readied their nerves, and entered the shell, with Noah taking the lead and holding a torch. Because of the shell's twist, they had to descend a spiral ramp. The walls, floor, and ceiling of the passage were perfectly smooth, without straight lines of any kind. It was like wandering through a narrow canyon carved by flash floods. Dirt and broken stone covered most of the floor, seeping in from the shell's opening. Luckily, this meant that Mira would have something to work with to use her spells.
The crab had been venting its shell for more than a week, but still smelled stale and earthy, like a mineshaft, while tinged with the biological signature of the parasites. It seemed there really was an ecosystem in the shell. The air seemed fine to breathe, and the torch was burning brightly. Was all that oxygen from the outside? How long could the oxygen last if the crab went back below the surface? How long did the dungeon crab live underground before surfacing? Either the crab and its parasites could function in an oxygen-poor environment, or something within the crab could produce a human-friendly atmosphere. Noah curiosity continued to grow.
They descended fifty feet when the first fork appeared, another tunnel branching off the staircase.
"We're going to keep going down, right?" Oath asked.
"Yeah, whatever passage leads us down, we'll take it."
One of the bipedal parasites burst from the branching tunnel, aiming for Noah. He stepped to the side to dodge, drew his short sword, and stabbed the beast through the spine when it landed.
The deeper they delved, the more branching tunnels they came across, but they continued their descent until reaching a large chamber at the bottom of the staircase, with five tunnels spread out. The staircase was wide enough for two people to walk shoulder-to-shoulder, but these tunnels were like subway lines. There were signs of adventurers coming through, marking the tunnels to try and keep track of which paths they had taken. There were also blood splatters, torn clothes, and a broken sword.
"What's that, hanging from the ceiling?" Oath asked. Above their heads, gooey threads glowed like fireflies, making Beth and Mira squirm in disgust.
"Cave worms. Their bodies are bioluminescent, attracting prey, which get caught in their threads like spider webs. This is a good thing. We won't need this." Noah extinguished the torch and stored it in his ring. "Ok, let's split up. We can cover more ground that way."
"Wait, WHAT?!" everyone exclaimed.
It was the hardest Noah laughed since coming to this new world. "Relax, I'm just kidding. Can you imagine? In all seriousness, let's take this path over here. It looks like it continues to slope."
They took the right-most path, further descending into the dungeon crab, and soon stopped at the entrance to a branch chamber, hearing movement within. They stayed against the wall to avoid attracting whatever was inside. Noah signaled to the others with his hand, cast his invisibility, and stepped into the doorway.
The sight before him was grotesque; a pile of football-sized maggots feasting upon the remains of slain adventurers. Their fat bodies quivered as they peeled flesh from bone. The walls were honeycombed to house the creatures between meals, and three adults were standing guard. The guards were bugs of some kind, consisting of four legs surrounding a head and torso with wings between the legs. The legs were armor-plated and sharp, and their downward-pointing faces had teeth like an angler fish. They looked almost like winged bar stools.
Noah drew his sword and killed one of the beasts without his presence detected. Seeing their comrade sliced in half, the other two began to panic and searched for the invisible assailant. He killed them as quickly as he had killed the first.
"Clear," Noah said as he released his spell.
He reappeared just as Oath and the others entered the room, immediately broadcasting their revulsion at the remains. Noah knocked the pile of bodies over and kicked away the maggots so that he could begin poking around with his sword.
"Don't loot them!" Oath said in disgust.
"Why? Because we didn't kill them? We're adventurers; we thrive on the deaths of others, be they humans or monsters. Meh, nothing great." He collected a few coins and arrows, but that was it.
"Hey, something's coming!" Trevor shouted. They ran out into the hall, hearing wingbeats. Further down the tunnel, several more four-legged bugs were flying toward them, likely detecting their comrades' deaths. "Phalanx Spears!" he then cast.
He blocked the passage with an array of mana blades, and Beth began launching arrows, but the armor plating on the monsters' legs proved too resilient, and they smashed their way through. Oath took down one, but a second tackled him from the side, tearing into him with its teeth and claws. Noah killed it before it could inflict more damage, then fended off the others with well-placed stabs. Trevor was on his back, with Beth and Mira working together to save him.
Noah was still on his feet, so the monsters headed toward him. He put away his longsword and instead switched to his short sword. The first bug that tried to tackle him met his shield and piercing blade, with the others dying the same way.
The battle ended, and healing potions were used where needed. This certainly was an interesting environment for fighting. Most of the monsters seen so far had hard outer shells, which Noah and his group had little experience dealing with. Their group focused on attacking rather than endurance, as they usually fought beasts as vulnerable as themselves. Aside from Noah's shield, the group didn't have much in defense outside of light armor--and a strong offense, of course.
They continued deeper, passing by countless branching tunnels and eventually coming to another fork. Before they could decide which path to take, they heard movement down one of the tunnels, and soon saw the source. It was a flood of centipedes, just like the one that had tried to kill Oath that morning.
"Holy shit!" Mira shrieked, something very out of character for her.
"Come on, this way!"
Noah ran down one of the passages with the others following, but so did the centipedes. It seemed they were familiar with the scent of people and now hungered for Noah's group. He slowed his pace, letting the others get past him, then untied a bag hanging from his belt and scattered its powdery contents across the floor.
It was lye, the best he could make within reason. It was much more caustic than what he had made in the forest with Tin, and when the centipedes ran through it, getting it on themselves and breathing it in, they immediately began to writhe and curl in pain. However, it barely slowed them down, and those in the back climbed over their ill kin.
The group kept running, though more monsters burst out of the tunnels ahead. Noah and Oath took them out to the best of their abilities, trying to incapacitate them with one slash each. Those not slain retreated immediately as the group passed by, not wanting to become the prey of the centipedes behind them.
"There's a room ahead!" said Trevor.
"Mira, wait until we reach that room, and if I give a signal, use your Earth Surge spell," said Noah.
