Gark saving throw: 4

Gark manages to barely stay standing under the onslaught.

Amiz, Valar, and Thelanis are up. The bugbear Gark fights Draíocht and a worg battles Amiz.

Amiz continues to attack with his axe

Attack: 13 Damage: 12

The worg takes a big hack to it's side. It strumbles for a second but stays on it's feet, snarling at Amiz.

Valar and Thelanis are up, the barely standing worg is about to bite Amiz, while Gark rages at Draíocht

Thelanis steps toward Gark, switching her hex to him and striking with her sword. 

Attack: 18 Damage: 12

Gark howls in rage. He's stumbling on his feet, almost ready to drop.

Valar is up.

Valar continues his attack: Attack: 10  Damage: 13

Gark slips out of the way, far more agile than he seems, he smashes you with his morningstar, as the worg bites at Amiz:

Morningstar against Valar Attack: 18 Damage: 9 Piercing

Bite against Amiz Attack: 10 Damage: 12 Piercing and Amiz must succeed on a DC 13 Strength saving throw or be knocked prone.

You all are up, the fighting rages through the cave.

Thelanis calls upon the darkness within to curse Gark more strongly and swipes her blade at him.

Bonus: Hexblade Curse on Gark
Action: Attack: 11 Damage: 14

Draíocht lunges at Gark with his maw wide open.

To-Hit: max(11,19) + 5 = 24
Damage: 3+1+3 = 7 piercing
On a hit Gark must make a DC 13 saving throw or be knocked prone.

Draíocht's teeth sink into Gark's neck and he lets out a yell as he is pulled to the ground, dead.

The worg is still up, however, and thrashing in anger now that all it's masters are dead.

Amiz and Valar are up.

Amiz attacks the worg with his axe.

Attack: 23 Damage: 10

And finally the last enemy goes down. The cave is littered with dead goblinoids and monstrous worgs. Alaine is breathing heavily in the corner while Liarona is still tied up in the corner of the room, "Untie me, cousin" she asks Draíocht plainly. Apart from a small crack above your heads, there are no other entrances or exits from the cave apart form the one you came in. 

Draíocht relaxes his ears and gives a pleased look to the party. A flawless victory. Excellent axe and swordwork from them.

He steps over to Liarona and carefully uses his canines to chew through the ropes without harming her. After doing so he lifts his head trying to get closer for a look/smell of the crack for any indication of what lies beyond it, using the heightened nose and ears of a dire wolf.

Perception: max(3,9) + 5 = 14

"Thank you cousin." She glares at the others, "Strange company you keep, but I suppose it takes beasts to fight beasts."

The gap in the cave roof smells strongly of the bugbear Gark, like he climbed up here often for some reason. He wouldn't be able to fit through, but he could certainly be storing something up there.

Draíocht moves his head between pointing at Gark and pointing at the ceiling in an attempt to convey the idea there may be something in the crack. 

[[ Human prejudice against non-humans was mentioned before. I'm guessing the reverse applies too? (Just checking if Liarona's sentiment is common.) ]]

Yep you’d know as an elf that the feeling mutual.

Valar will clean the gore from his blade, then search the bodies and the room. Perception: 1

Shrugging, he will ask if anyone needs healing

Thelanis also searches things, after shrugging and saying, "I'm okay, just a little scrape", to Valar.

Perception: 16 Investigation: 13

These particular goblinoids have very little money on them. Gark has nothing on him, while the goblin's all have just a few coins:

32cp, 17sp.

One of the goblin's has a bit of folded cloth that, when unfolded, turns into a stylish cap. Clearly looted from some fancy prisoner.
