The remaining goblin underling fires upon Tessa:
Shortbow Attack vs. Tessa: 9. Hit: 5 piercing damage.

Quinn is up! Sir Roderick has a fresh death roll...

(Holding Tessa's attack, if she's still up, until after the wolves in initiative.)

Syzygy stumbles forward, as lightning springs from his hand to deliver a powerful shock to Errk. Errk goes down, howling. (One boss down!)

(I think Tessa's down... Quinn is up! Sir Roderick has another roll...Yeemik and one goblin archer remain.)

18- Death Save Sir Roderick.

Quinn steps on the chest of the goblin he just felled for leverage and pulls his axe from their body. He turns and sets his sights on the goblin underling who just attacked Tessa. Quinn draws his dagger in his offhand, charges his target and unleashes a slash with his axe followed by a stab with his dagger.

Move: Full movement to get within melee range of the remaining goblin underling.

Attack: One handed melee attack with his battle axe. 13 to hit for 5 damage.

Bonus Action: Off hand attack with his dagger. 22 to hit for 3 damage.

(Yes, she's down)

Tessa: Death Save 18

Hoping over Jurgen's unconscious form, Quinn's axe is met with the goblin's shield, but Quinn's dagger slips through. It is wounded, but not mortally.

The two wolves charge in. One stops to sniff Klarg's head. The other growls menacingly at Syzygy.

Yeemik runs along the top of the shelf, then clambers down the stone steps. Looking between Syzygy and Quinn, Yeemik chooses Quinn. He hops off the steps and flanks his goblin archer before launching an attack upon Quinn:
Yeemik Scimitar Attack #1 vs. Quinn: 18. Hit:7 slashing damage.
Yeemik Scimitar Attack #2 vs. Quinn: 12. Hit:8 slashing damage.

Syzygy is up next (but make another Animal Handling check first, especially if he wants to use his movement or other sudden moves...)

Syzygy commands the wolves to "Sit!" 
Animal Handling: 2 + 1 = 3

Then, with a word and a gentle wave of the hand he casts moon fire on the two remaining goblins. 
8 radiant damage. 14 Dex Save

A ghostly flame-like radiance descends on the two remaining goblins, as the growling behind Syzygy increases in pitch.

DC14 Dex saves (or take 8 radiant damage):  Goblin: 15.  Yeemik: 21 

The goblin collapses. Yeemik, now alone, is looking badly hurt and eyes the wolves for aid (or is it the exit behind them?)

Prisoner death save: 1

Quinn is up again!

Quinn parries one attack, but cannot parry the other. He's bloodied and loosing strength. He digs deep and musters the strength for, perhaps, one last attack. He slashes at the goblin boss with his battle axe and then stabs with his dagger.

Action: one handed attack with his battle axe. 23 to hit for 8 damage.

Bonus action: off-hand dagger attack. 15 to hit for 4 damage.

Quinn beheads Yeemik with a powerful swing. The goblins are all dead. (But we're not out of initiative quite yet...)

Sir Roderick, Tessa, and Bryony may each make another Death Save (Sir Roderick is currently at two failures, one success.)

The wolf harassing Syzygy finally jumps him. 
Bite Attack vs. Syzygy: 9. Hit: 7 piercing damage and must succeed on a DC 11 Strength saving throw or be knocked prone.

The other wolf looks warily between its kin, Syzygy, and the head it was sniffing. (The third wolf is still down the tunnel somewhere.)

Then, Syzygy may act (if he's up...)

Quinn and Syzygy are the last two standing. The dark, smoky cave is a sea of carnage - with the dead and the dying everywhere: The bodies of eight goblins, four humans, a halfling, a kobold, and the disembodied head of a bugbear king sprawled across the filthy floor in a bloody diorama of death.

Two wolves sniff around, one acting rather aggressively with Syzygy (who just carefully dodged the sudden snapping jaws at his ankle.)

Their comrades are in bad shape, and may be already dead. (Sir Roderick looks the worst off, with an arrow through his throat.)

Sir Roderick, Tessa, and Bryony should each make another Death Save. (Sir Roderick will expire if he doesn't succeed.)
Human prisoner death save: 15

Then, Syzygy and Quinn may act. (Syzygy should roll another DC5 Animal Handling check to avoid another attack from the aggressive wolf, or a DC15 Animal Handling check as his action to try to permanently calm the wolf – at advantage if he has any more food to give. He may, of course, also attack it if he chooses, instead.)

Bryony Death Save - 15

Sir Roderick- 1

( Well....such is life.)

Sir Roderick's gurgling stops. He is no more.

Tessa should make her Death Save, and Syzygy and Quinn may act. (Syzygy first with another Animal Handling check.) 

Inside every Shadar-kai there are two wolves. Today, Syzygy is not the alpha.

He has already given every scrap of food. Now, he kneels in submission, eyes to the floor, lowest and without threat. Just a pup looking for a pack.  “There, there,” he says in soothing tones to the wolves (but actually addresses) Quinn, “any rations left Quinn?” 

Animal handling: Nat 20 + 1

[writing this part after I rolled the Nat 20: Syzygy having nostalgic flashback montage of the long journey he’s been on with the wolves, the ups and downs]

Tessa

Death save: 12

"Careful, friend...I'm afraid I don't have any rations."

Just then, the ranger see's a subtle, yet perceptible shift in the wolves. 

"Whatever you're doing...keep doing it. I have to check on our friends."

Quinn will move slowly and methodically, avoiding eye contact with the wolves. He eyes Tessa, but her proximity to the wolves concerns him so he decides to go for Bryony. Quinn moves up the stone stairs to aid his friend. He finds young Bryony lying on the floor bleeding and her breath shallow. He digs out on of the ornate glass bottles he found in King Klarg's stash. He swirls the liquid and watches it shimmer. He unplugs the bottle, craddles the back of her head and slowly pours the contents into her mouth. 

He traces the shape of a swirl on her forehead and whispers a silent prayer to Melora.

Syzygy drops in submission and calms the wolf harassing him. 

Quinn clambers up the crude stone steps and feeds Bryony the red elixir he found. His hunch turns out to be correct. She awakens, her wounds suddenly closed, healing 5 hit points.

Syzygy's wolf joins its companion, sniffing Klarg's head.

Tessa may make another Death Save. (She has two successes, no failures, so far.)

Then, Bryony, prone, may act, as may Syzygy.

Jurgen slumbers on.
