WHAT the fuck.

Negative channels are actually amazing for swarms and he doesn't have them anymore. The mace is going to do fuckall unless he specifically swats a wasp against a wall with it. He could try blinding the wasps with Burst of Radiance but if any of those hapless people are Evil it'll hit them too and the wasps certainly are not Evil.

He's just going to scramble for a less stupid position and cast Prayer and hope somebody has a better idea than Creating Water at the bugs.

...The bugs are actually ignoring him specifically. In fact, the bugs nearest where he arrived paused, looked at him for a moment, and then went back to stinging People Who Are Not Him. 

One of the four-armed humanoids holds up a holy* symbol whose actual design is obscured by wasps, and channels negative. They're good at it; only wasps are effected. Some of them fall to the ground, dead. More don't. 

...maybe these people offended Calistria. Underground. He would sort of have expected Her to have a different weapon underground, he heard a story about someone getting attacked by jellyfish when they offended Calistria in the ocean.

Still, the probably-evil party of humanoids is way likelier to tell him where the fuck he is than the wasps are, or than Calistria is. He'll start Creating Water at the wasps.

...The wasps aren't perfect at avoiding this or anything, but after the first couple of Create Waters they cease to be flat-footed about it, in a way that normally bugs are not. 

A couple of wasps pick up silk cords and, coordinating in a way that again, Bugs Usually Do Not, begin binding ambiguously evil humanoids that are downed but not dead. 

........that's so weird?????

Are any of the humanoids acknowledging that he is here and trying to help them literally at all.

Well mostly they are more concerned with attempting to deal with the wasps but that one evil cleric did deliberately leave him out of the negative energy channel. 

A winged figure who visibly parses as a paladin strides around a corner, holding a polearm that looks sort of like an extra-spiky glaive. The remainder of the wasps abandon their assault on the remaining probably-evil humanoids in order to join their fellows in trussing them up, a process in which they are aided by a handful of spiders who scuttle in from the same direction as the paladin. 

...who is this a paladin of.

His holy symbol is a round, polished disk of wood with a stylized fish skeleton carved into it. 

He uses the blunt side of his polearm to club down the cleric after he fails to surrender, and then turns and says something incomprehensible to Blai. 

The thing is it's actually pretty hard to identify a paladin by looking. A person with a holy symbol and armor could be a cleric - Blai has a holy symbol and armor, and is a cleric - and a cleric could be of anybody. If they have a horse it means they have a horse, it's not like the horses look like anything special. If they're not scared it means they're not scared, people who aren't Blai have sometimes quite extended periods in which they're not scared and even Blai you can't tell by checking his face. If they hit something Evil really hard it could mean they're lucky. You have to see them lay on hands, or put Detect Magic up and watch them spam Detect Evil, or something, to be sure they're a paladin specifically. Identifying them as a cleric is nearly as good if you recognize the holy symbol and Blai does not. A fish skeleton!

However, this person is taking prisoners, might be controlling the wasps such that they excluded a random bystander rather than stinging them too as collateral damage, and is trying to talk to Blai without doing it at swordpoint. All good signs.

Blai puts his hands up and says, "I speak Chelish, Common Taldane, and Infernal. I'm a cleric of Iomedae."

...If the paladin understands or recognizes any of those languages he sure doesn't indicate it with his facial expressions. He tries several of his own. 

Headshake. Apologetically: "I did not prepare Comprehend Languages." Maybe they also call Comprehend Languages after its verbal component.

He gives a wry smile and dips his head, which is more comprehension than he's shown so far. 

He contemplates this for a moment, then says, "Ansuzu," gestures at the now entirely bound prisoners, and gives him a questioning look. 

Blank incomprehension? Is that the answer he was looking for?

Seems like it! He looks reasonably satisfied, and calls something back through the caves, including a phrase that is recognizably 'Comprehend Languages' albeit pronounced slightly differently for reasons of accent. 

A tall woman, also with wings and funny ears, walks in and says something dry to the ?paladin?

She can be presumed to be the one controlling the crawly critters from the number of them currently crawling on, or buzzing around, her. 

Oh that's so disturbing. Why is this happening. He is going to keep his hands up but he is going to have to spend slightly more brain cycles on doing that.

The maybe-paladin and the bug lady exchange a handful more sentences, then turn back the way they came. The bug lady gestures for Blai to put his arms down and follow them. 

Okay. Are they bringing the prisoners too?

Not personally, but before long they meet a party of more winged people going in the other direction. Most of them are strong-looking or have contraptions of some kind for prisoner transport. At least, they're probably for prisoner transport. The difference between the underground equivalent of a cart and a contraption you lock someone in to starve them to death can be a little unclear to someone who's unfamiliar with the former. 

He does not have the words to follow up on that!

Eventually they make it out of the tunnels and into daylight. Another winged figure flies down to meet them and hands bug lady a medallion on a silk cord. She takes off the necklace she's currently wearing and puts on the new one. 

"Alright, that should do it. Hello." 

His estimation of the wealth of this adventuring party shoots up! Is that a fucking necklace of Tongues! That they had spare! "Hello. I'm Select Blai Artigas, I'm a cleric of Iomedae, I don't know where I am, I apologize if I misinterpreted the situation with the wasps."

"I don't know how you interpreted the wasps. I'm Taylor Haribert, witch. You're on the Villarosa side of the border between Villarosa and Mykorrizyme. I don't know the name Iomedae."

"...she's a saint of Aroden?"

"...'Aroden' sounds familiar but I'm not quite placing it. What's Iomedae's alignment?"
