The party makes camp that night in a shallow grotto where the bioluminescent fungi grow thick enough to read by — not that anyone is reading except Gale, who is always reading, and Astarion, who has claimed the Necromancy of Thay and sits apart with the book balanced on his knee, your safety protocol in effect: he reads, you watch, and if his skin sparks purple, you're ready to cut the line.

It hasn't sparked yet. But he glances up every few pages and catches your eye across the camp, and the glance is different from his usual theatrical check-ins. Quicker. Less arranged. Like he's confirming you're there, not performing the act of looking.

Karlach has adopted the cooking rotation from Gale — or more accurately, has appointed herself sous-chef, which means she chops things with an axe while Gale winces. The stew is good. The company is better. Shadowheart sits close to the fire for the first time, not joining the conversation but not actively blocking it either, and when Karlach passes her a bowl, she takes it without comment. Progress.

Lae'zel sharpens her greatsword and says nothing. You've come to appreciate Lae'zel's silences — they're honest. No performance, no subtext. Just a warrior doing maintenance. There's a simplicity to her that you find restful.

You fall asleep with the cub on your chest and Mama's bulk between you and the dark. Somewhere beyond the fungi, the Underdark breathes — slow, vast, ancient — and the sound is not threatening. Just big.

The Underdark is — beautiful.

You didn't expect that. You expected darkness, danger, the oppressive weight of a million tons of rock above your head. And those things are here. But so is this: bioluminescent forests that paint the cavern ceiling in shifting shades of blue and violet, mushrooms the size of houses that pulse with soft internal light, crystal formations that catch your kinetic field and scatter it into rainbows.

The air smells different down here — thick, mineral, humid, with an undercurrent of something organic and alive. Mycelium networks carpet the ground in pale webs, and when you step on them, they release puffs of spores that glow briefly before fading.

You walk. You learn.

Tav — Martial Grounding:

"Teach me the stance," you say, falling into step beside Tav during a rest.

Tav looks at you — assessingly, but not unkindly. "The shield stance?"

"The one where you let the impact flow through instead of stopping it."

Tav nods. Demonstrates. The key is the legs — not braced rigid, but bent, flexible, the weight distributed on a wide base. "If your center of gravity is too high, the kinetic impact flips you over. Treat your legs like roots. Drive your trailing heel into the dirt, bend your lead knee."

You copy the stance. Tav adjusts your hip angle, taps your trailing heel into position.

"Now — shove me."

You give a moderate telekinetic push. Tav absorbs it — rocks back, then forward, the force flowing through their stance like water through a riverbed. No resistance. No fight. Just redirection.

You apply it to your own shoves immediately. The next time you need to brace against a recoil, you use Tav's stance, and the force that would have driven you backward instead sinks through your legs into the ground.

Karlach — Brotherhood:

Karlach walks beside you for a while, her engine humming warm against your kinetic field. She doesn't teach — she talks. About Avernus. About the years she lost. About the engine in her chest that keeps her alive and keeps her isolated in the same breath.

"We're the same, you know," she says, quietly for her. "Borrowed time. Both of us. You with your brain trying to blow itself up every time you use it, me with this thing —" she taps her sternum "— counting down to zero."

"And?"

"And nothing. Just — we go out swinging. Right?"

"Was there ever another option?"

She grins. Bumps your shoulder with hers — gently, because the alternative is dislocating your arm. "I like you, kid."

"Stop calling me kid. I'm not that much younger than you."

"You're mortal. Everyone mortal is a kid to me."

Lae'zel — Economy of Force:

You ask about her swordsmanship during a march through a crystal corridor. Lae'zel regards you with the flat, evaluative stare of a drill sergeant assessing a recruit.

"True martial superiority," she says, "requires you to yield to the momentum of the weapon, guiding its path rather than forcing it."

You translate: "Leverage. If the rock is heavy, don't lift it — lean into it."

A beat. Then Lae'zel makes a sound — a short, sharp exhalation through her nose that might be a scoff or might be the closest a Githyanki warrior comes to saying yes, precisely.

"Chk. You learn faster than most istik."

You file istik under probably an insult, possibly a compliment, definitely Lae'zel.

Gale — The Textbook:

"Can I borrow a book?"

Gale nearly drops his staff. He turns to face you with an expression of such profound, radiant delight that you briefly wonder if you've accidentally proposed marriage.

"A book?" he repeats, as if the word is a rare vintage he hasn't tasted in years. "You want — you want to learn? From a book?"

"I want to learn containment theory. The geometry you use to focus your missiles. The mental dam thing at the base of the throat."

He practically vibrates. Within thirty seconds, he has produced — from somewhere deep in his pack, probably a pocket dimension reserved exclusively for literature — a battered volume titled The Fundamentals of Evocation and Somatic Scripting.

"Chapter three is the containment matrix," he says, marking pages with scraps of parchment as he talks. "Chapter seven covers the somatic dam technique. Chapter twelve — skip chapter twelve, it's outdated. Appendix B has the geometric proofs, which —"

"Gale."

"Yes?"

"Thank you."

He beams. It's the most genuine expression you've seen on his face — not the self-aware pomposity of Gale of Waterdeep, but the simple, uncomplicated joy of a man who loves teaching and has just been handed a willing student.

You study the book while walking. This is inadvisable — the Underdark floor is uneven, poorly lit, and actively hostile — but your brain has always been better at multitasking than at caution.

The containment dam clicks on page forty-seven. Not gradually — clicks, like a key turning in a lock. The mental technique Gale describes — a focused constriction at the base of the throat, where the psychic channel narrows, creating a bottleneck that forces the kinetic energy to compress before release — maps perfectly onto what your body has been doing instinctively. The difference is control: instead of the energy blowing through the bottleneck in a chaotic spray, the dam lets you regulate the flow.

You test it an hour later, when the party encounters a Hook Horror.

The creature bursts from a side tunnel — all chitin and hooks and the screeching fury of a predator interrupted during dinner. It's big enough to fill the corridor, and it's fast, and it's heading straight for Shadowheart.

You don't think. You drop into Tav's grounding stance — low center, trailing heel in the dirt. You trace Gale's containment geometry — not the wide circle you used for the spider, but a tight, focused triangle. You compress the force through the mental dam, feel it condense, feel it aim.

Then you drop a boulder.

Not on the Horror — above it. The boulder strikes a cluster of volatile orange mushrooms on the ceiling, and the mushrooms — because the Underdark is a place where even the plant life is trying to kill you — detonate in a chain-reaction explosion that fills the corridor with fire and concussive force.

The Hook Horror staggers. Screams. Collapses.

You stand in Tav's stance, hands lowered, breathing normally.

No migraine. No nosebleed. No purple sparks. Just — contained force, directed precisely, with zero kinetic feedback.

"Did that just —" you start.

"Zero migraine," Gale confirms, and he's grinning. "Perfect containment. You used the somatic dam."

"I used your book."

"You used my book." His voice is thick with something dangerously close to parental pride. "Chapter three. The compression matrix. Applied in field conditions on the first attempt. That is — I mean, I don't want to overstate — but that is genuinely remarkable."

"It's a good book," you say, and tuck it back into your pack.

Gale turns away, and you catch him wiping his eye. He will later deny this. You will let him.

Shadowheart — Earned, Not Given:

You've noticed Shadowheart's techniques since the Blighted Village — the way she positions herself in doorways, the way she breaks up her outline against dark stone, the way she seems to become part of the shadow rather than simply standing in it.

You asked about it once. Her response was a flat, measured look and three words: "My methods are my own."

So you stopped asking. You didn't push. You didn't pry about Shar, about the artifact she keeps hidden in her pack, about the guarded wariness that wraps around her like armor.

Instead, you just — existed near her. Protected the camp without being asked. Treated her secrets with the same casual disregard you treat everything: You worship a dark goddess? Cool. Not my business.

It takes eight days.

On the eighth night, during a march through a narrow tunnel where the bioluminescent fungi give just enough light to see by, Shadowheart falls into step beside you.

"You're too loud in the dark," she says, without preamble.

You wait.

"Come here." She positions you against a wall — dark stone, rough-textured. "The shadows aren't just empty space. They are a cloak. Align your silhouette with the dark stone so the light doesn't catch the edge of your armor. Break up your outline."

You adjust your stance. Tilt your shoulder. Press your back against the stone.

"Better," she says. And walks away.

She doesn't compliment you. She doesn't explain why she changed her mind. But the lesson was a gift, and you both know it.

Astarion tucks a glowing mushroom in your hair.

You're walking through a cavern of particularly spectacular bioluminescence — blue and violet and pale green, the mushroom caps pulsing with internal light that makes the entire space look like the inside of a jewelry box. You're reading Gale's book, weaving between stalagmites on autopilot, trusting your peripheral vision to handle navigation.

You don't see him approach. You feel the cold at your shoulder — his perpetual absence of warmth — and then a faint tug at your hair, and when you reach up, your fingers find a small, glowing blue mushroom cap nestled in the strands behind your ear.

You turn. He's already walking away, hands clasped behind his back, expression deliberately neutral.

"Did you just put a mushroom in my hair?"

"I have no idea what you're talking about."

"It's glowing. I can feel it glowing."

"Perhaps your hair is simply that luminous. I've heard stress can do extraordinary things to follicles."

You stare at his back. He doesn't turn around. But his shoulders have a particular set to them — not the rigid posture of performance, but something looser. Something that looks almost like caught.

You leave the mushroom where it is.

It stays luminous for three days. You know this because you count.

The days after the Hook Horror have a different texture. The group moves deeper into the Underdark — navigating caverns where the ceiling drips with something that might be water and might be digestive fluid, skirting colonies of zurkhwood where the mushroom-trees grow taller than buildings and the spores hang in the air like lazy snow. Lae'zel leads, because Lae'zel always leads, and Gale maps, because Gale has turned cartography into a coping mechanism. Shadowheart walks point with her mace out, and Karlach brings up the rear, humming Avernus war hymns that she insists are lullabies.

You walk somewhere in the middle. Mama trots at your ankle, the owlbear cub perched on her back like a feathered prince being carried through his kingdom. Astarion walks wherever you walk, which is new. Not beside you — never that obvious. A few steps behind, or slightly ahead, or on the opposite side of the cavern in a position that just happens to keep you in his sightline at all times. You notice because noticing is what you do.

He stops performing.

Not all at once. Not a dramatic reveal. It's gradual — the way a tide goes out, not the way a dam breaks. He makes fewer quips. Drops fewer innuendos. When he does speak, the words are sharper, drier, closer to something real. One night you catch him watching the campfire with no expression at all — not the practiced smirk, not the theatrical boredom, just nothing — and when he sees you looking, the mask snaps back so fast you almost hear it click.

But you saw. And he knows you saw.

Small things accumulate. He brings you a water flask without being asked — sets it beside you and walks away before you can comment. He spots a weakened ceiling in a tunnel and redirects the group's path with a casual "this way looks less collapse-adjacent" that saves everyone's lives without him ever acknowledging it. He cleans your borrowed dagger one morning while you're rolling up your bedroll, and when you pick it up and find the edge sharper than you left it, he's suddenly very interested in studying his own fingernails.

You don't mention any of it. You don't need to. You've learned that Astarion's kindness is a skittish thing — if you shine a light on it, it bolts. So you accept the flask. Walk the safer path. Use the sharper blade. And if your chest does something complicated every time you catch him doing something kind when he thinks no one is watching — that's your problem, not his.

The mushroom in your hair stops glowing on day three. You leave it anyway, dried and brittle in the strands behind your ear, and you tell yourself it's because it doesn't bother you.

You are an excellent liar. But only to yourself.
