(Combat recaps continue to be hard. Doing my best with the notes I got, ya know?)
The gang is still fighting Azher when they notice the final shield dissipate from around the soul turbine. Guess the Guardians came through! We are, however, too occupied to text them our appreciation. Time for everyone to take a free action, because of fate and stuff. Everyone seems to have a cool and normal time with their free actions except Null. Recently revivified Null has ultra-low HP you see and so tries to remedy that by using her action to take a potion of supreme healing. Sucks to be her, because the unshielded turbine has a lil arcane UNO reverse when it comes to nearby healing magics. This chick drops to 0 HP again and this time Azher looks hella compelled to make this a permanent arrangement for his wayward science experiment. Bro's gonna be disappointed though, because in an absolute KING move Silas swoops in and Dimension Doors his friend a couple hundred feet away from the turbine. He rouses her and tells her to wait until he can bring them back to the fight. Grateful, Null will chug a couple health potions until Silas DD's them back to scrap.
Meanwhile, back at the turbine, things are not going well. Alistair victimizes Flynn until he hits 0 HP and then kills Berrik! Lotty tries to do some rapid distance math and reflect on whether her dead pal is an object. Azher casts Invulnerability on himself, knowing the wizard was the last one with a chance of dispelling it. Lotty finishes her equations and casts Haste on herself, grabbing Berrik and dragging him as far as she can away from the turbine. Silas and Null DD back to the fight, appearing right next to Lotty and dead!Berrik. Azher Feebleminds Silas, but a Greater Restoration potion solves that real quick. Silas continues his MVP world tour and crushes white exaltium in order to be able to Dimension Door two more of his friends to safety. Strangely the exaltium's wild magic affects Lotty, allowing her to immediately cast Arcane Gate. A portal appears in front of the trio, with another popping up next to a still-downed Flynn. Clocking an opportunity to get Flynn away from a potential killing blow, Null runs over and drags him through the portal. The duo appear next to their friends. Null snatches a potion from dead!Berrik's bandolier and pours it into Flynn's mouth, bringing him up. She then turns around and leaves back through the gate to take Azher's attention off of our little recuperation station. Lotty gets Berrik back to the land of the living. Flynn heals up and rejoins the fight. Berrik, now fully amped for wizard on wizard violence, steps through the gate. He dispels Azher's invulnerability and then finishes off with a Healing Word (Reminder: healing magic hurts Azher).
We're back in it, babes! The Ashen Company is off to the killing races again. A bit more fighting happens. We continue trying to shrug off lair actions. Lotty spots a strange but familiar figure from the mountain, a dwarven chef being piloted by a rat. She feels inspired? Null yeets Azher into the turbine with fate stuff, but the damage is necrotic so the cinematic falls flat. Azher keeps trying to villain monologue us, but fate steps in and we feel replenished, like we've each gotten a full night's rest in the past 6 seconds. SO WEIRD.
In the end, it's Null who gets the killing blow. She sweeps his legs and knocks him prone, stepping on his wrists to stop any last minute somatic attempts. Null brings down the blade of Reaper's Scream into his open mouth before he can speak another word - no spells, no threats, no laughter. Alistair's demise sends a shockwave through the entire chamber, forcing everyone to make saving throws. Lotty falls unconscious, but everyone else stays up and instead takes massive amounts of force damage.
Berrik and Silas heal up Lotty right away. A somewhat dazed Null keeps stabbing the now-still corpse of her lifelong tormentor. Is this a blatant homage to Buffy the Vampire Slayer S2 E01, when Buffy finds an outlet for her trauma by destroying the bones of the Master? Maybe, but there's no catharsis to be found here for our gal Null. Flynn discreetly texts Ezra that it's time to do his thing. The soul turbine hums along. We'll have to do something soon.
