What is surprising is the nature of the summon. It's an absolutely enormous bird with a lizardlike tail, brightly colored feathers on its back and wings, and an unusually scaly and featherless body.

There is also a woman in some unfamiliar red-and-black military uniform on its back.

Like every other non-Jubjub member of this situation, she is in fact surprised. Getting Plane Shifted into another Material-ish plane by a mis-cast combat spell, and then subsequently arriving plausibly as part of a summon, is not supposed to happen. She's not supposed to be summonable and she doesn't feel the sense of safety she hears that summons feel. And something important feels missing, though she doesn't have a good feel for what, but whatever it is has got to be way less important than the SHEER QUANTITY OF DAEMONS HERE. Gods fucking devour it.

She'll try to cast Fly on herself, because she doesn't seem to have a good path to staying on or climbing off of this bird-monster and you don't want to be grounded during an aerial battle. Thank Asmodeus for her concentration practice.

Get oriented.

There's a bunch of fae and forest-dwellers fighting the daemons. Adventuring party with a paladin at the center of the mess, which is a problem for Future Carissa if she has the privilege of existing. She's behind some perimeters, which is good, but the perimeters aren't very solid and they certainly aren't aerial. There's some shouting in what sounds like Sylvan.

Party repositions, including a lantern archon. Apprentice wizard does some spellcasting. Party wizard also does some spellcasting with a rod, which is apparently a Haste effect even though it doesn't look too familiar. (This applies to the bird-monster but not Carissa. She's going to be glad for that Fly spell.) Lantern archon targets the Jubjub with a ray, presumably a friendly one. Winged jackal tries to drag some green guy out of a tent full of daemons. Lightning hits a bunch of daemons. Land in the distance starts getting tangly. Wall of force shows up. Trees and treants and centaurs attack some daemons, two of which fall. Largest treant shakes off some daemons.

Specialist thanadaemon teleports to the birdcage area and the team is finally ready for the ritual! They get to work. Another thanadaemon beats up Devarre (the green guy) with an energy-draining quarterstaff. Genthodaemons in their role as combat generalists move and defend the bibliodaemons. Astradaemons go for Vinroot (the largest treant) again, and get in a decent attack before ending up entangled with each other.

Wizard's apprentice hands the plant adventurer what looks like some pre-measured packets of powdered silver.

And a significant amount of power very visibly flows through the plant adventurer, expending the silver, and causing the not-in-touch-range very large treant to look significantly more combat-ready.

Seems kind of like an obscure lower-circle variant of Death Ward specifically targeting daemons Carissa saw a while back? But that's touch-range. And if you'd had an anti-daemon ward prepared, wouldn't you have used it earlier and not bothered putting ranged metamagic on it? It has a duration in minutes, not rounds.

The power has flowed and now the plant adventurer seems to be trying to communicate with the bird-monster. Probably a ranger or druid, then.

Bird-monster moves at speed a bit southwest of the songbird enclosure.

The adventurers seem to be trying to be out of an 80'-ish radius of the bird-monster. Does Carissa want to join them?

Also, that same conspicuous and strange power goes through the presumably-a-paladin, leaving her dusted in silver. Same casting motions the plant used for the daemon-ward-ish effect.

Yes (while hastily shoving her red pentagram into a pouch). And she'll target herself with Tongues.

This is good timing on her part, because the bird-monster is opening its mouth.

Screeeeeeeeeeech

The screech is definitely loud. That part is easy to describe. It also feels deeply unforgettable. It pierces straight into the soul, even from the distance Carissa and the adventurers are at. Even time and thought seem to briefly stop during the screech, which you'd think would be detectable via spell durations, except those may have paused in their countdowns to admire the bird.

Everyone in the radius Carissa just left, except for the Jubjub, is stunned. One of the thanadaemons has vanished. The ritual seems thoroughly disrupted.

Oddly enough, the screech doesn't seem to have disrupted Carissa's hearing at all.

Her head does hurt, though, and there's spots in her vision, and she feels kind of dizzy. Probably this is normal, though, and she shouldn't look weak in front of the adventurers coordinating things.

She'll turn to the wizard and speak in … she thinks it's Sylvan. "Not a standard summons, do want the daemons gone. Orders?"

More lightning strikes on daemons. Largest treant does something with a beam that doesn't work very well.

Wizard's apprentice casts Message on Carissa. "What are your capabilities?"

Vinroot continues being unfortunately resistant to energy drain. Genthodaemon generalist drops in on the dryad circle. Bibliodaemons teleport in on the planned targets for informational cleanup and the, er, unexpected surprise entity of unknown informational state.

The cacodaemon with Kenchlo's soul reports to the Obcisidaemon, who stabs it and the soul gem within before teleporting off to more thoroughly resolve the issue of Kenchlo.

She can't mention Infernal Healing, can she. Ah well. "I have Haste, Summon Monster 2, Resist Energy, Rope Trick, Greater Detect Magic, Comprehend Languages, Feather Fall, and cantrips. I'm also a skilled crafter who would be happy to work for you as payment after this."

Things are terrifying and her vision is getting even worse and she wants to hyperventilate but she will not, because she needs to look valuable to the higher-level adventurers to have the best chance of living through this.

Green guy heals the paladin, who uses lay-on-hands on herself, probably ending Carissa's uncertainty. Paladin hits daemon hard. Wood-textured snake summon shows up and attacks another daemon, not that effectively. Wizard casts a spell, dumps another daemon in a pit, rushes towards some fae. Winged jackal attacks a daemon, not that effectively.

Carissa is included on a message channel. "Bibliodaemons are trying to mess with our books. I'm trying to get out of their range." A different voice cuts in. "Bibliodaemons are the weaselly ones. Death by paperwork. Stronger than they look. Report attempted memory alteration."

Jubjub claws and bites a thanadaemon. For no clear reason, its plumage shifts wildly before settling on purple and white spiral polka dots.

The plant is apparently a druid, because ey has just turned into a dire tiger. Specifically, a celestial dire tiger. Which is now getting in the weasel, er, bibliodaemons' faces.

The fight is getting beyond Carissa's ability to track at this point. Bibliodaemons are teleporting? The loud bird swallowed a thanadaemon whole except for its staff? Something something wind and lightning? Someone's talking over message… oh, huh. Yelling 'report'. That's probably important … but daemons are important too…

Carissa manages to mutter "dizzy…" over Message before losing consciousness. She's starting to look kind of blue.

Well, that's bad. And also makes little sense, the daemons haven't been prioritizing her and there's not any obvious poison going around. For someone who looks like she's asphyxiating this person is still visibly breathing. …well, maybe something with breathing isn't working.

The party is not going to lose another person today, especially not an outside-context person. Mythic power to spontaneously cast Concealed Breath.

And the person looks stable, at least for a bit.
