"Right. We'll be taking a look and seeing if we can figure out what's going on."

"Okay. Bye!" Its head dips back under the water, and the otyugh glides away.

"Strange creatures..." Navarro mutters.

"Helpful, though. Both to us and in general, I've heard what sewer systems without them can be like." And why are humans so precious about things being dirtier than they are anyway, it's their own filth. No drow wants to do this kind of work either, but if someone does you take that and be happy, you don't insult them for it. There are enough other things to take issue with.

...she might be being unfair here, strange is a perfectly accurate description. Even so.

"A long swim to the left... is anything there on your map, detective?"

"Hmm... it could be many things. There's an old cave-in that used to connect to some other part of the sewers. There are sealed passages that head down deeper into the Vaults. Some old commercial basements have access tunnels. Not sure why they ever built those."

"I think we ought to head in that general direction, then."

He nods.

Navarro leads them through the lower sewers. These tunnels are bigger than those above, and they don't wind nearly as much. The water is essentially a branching, underground river. Tencednil's shadow nearly constantly detects movement beneath the water, but none of it seems to notice them as they walk along the winding paths.

After about thirty minutes of walking, they reach a dead end.

"The caved-in tunnel. I'm going to take a sample of the water." He unstoppers a vial, crouching down and filling it—

Tencednil's shadow detects three small shapes in the water, rushing toward them!

The shadow flickers through shapes... and she recognizes them. <Three! There!>

Since when did it know Drow Sign? That's new. More importantly, though— "Up! Three, coming from the water! Possible hostile!"

He quickly pulls his hand back and pockets the vial. "On guard, everyone!"

<Spray! Here!>

Well, it is the thing which knows where the... whatevers... are. She's not going to shoot acid into the water. Forward, and Color Spray.

The underwater creatures scatter! They don't seem affected by her color spray.

<Zero! Them grab poison!>

Zero? What does that... she sees one moving. Ah. She got zero. And grab poison... she doesn't have poison, and shouldn't be grabbing anything, so—

"They shook the Spray! Beware grabbing, and they're poisonous!" Yes she's badly positioned given that, she knows, that's what you get when both of the things she tried to catch managed to resist. And her Color Spray had been so consistent in the past, too. Well, that's what she gets for being overconfident.

A strange creature, with the front of a lobster and the back of an eel, leaps from the water and lands in front of Tencednil!

It tries to claw at her, but is much less graceful outside of the water. Neither of its claws hit.

Shadi slices the creature across its side with her sickle. It bleeds.

Navarro pulls his rapier from its holster and skewers the creature straight through the eye. It flails around before falling still.

"Reefclaws! Don't let them touch you!"

Garril holds his warhammer and eyes the water, waiting...

A second reefclaw lunges for him! One of its claws snaps onto his arm, and in one motion it wraps its body around his neck, slowly tightening like a vice!

Garril swings the hammer, but can't quite hit the damn thing! It's too close!

The final reefclaw bursts from the water. It slams into Navarro, twisting around his body and slicing into his side.
 

Fortunately, the reefclaws have positioned themselves very conveniently for her. Inconvenient for the others, perhaps, but she may yet resolve that. Color Spray?

The reefclaw on Garril goes still and slides off his neck. The one on Navarro screeches angrily but is otherwise unaffected.
