Two of the four goblins are glowing with light.

I'm going to attempt to run this combat in theatre of the mind, without a battle map. I will attempt to explain as clearly as possible as i go but feel free to clarify things with me and try things using your understanding of the environment.

Gark commands the goblins to attack while throwing one of his javelins, "Kill them, for Lord g'Ruek!" The goblins rush forward, the two glowing with light rush forward with their scimitars, while the other two stay back near Gark, shooting their shortbows. The worgs close to attack as well, but one of them is blocked from attacking due to the goblins in melee.

Gark Javelin Attack against Amiz: 17 Damage: 5 Piercing

Glowing Goblin 1 Scimitar Attack against Amiz: 22 Damage: 8 Slashing

Glowing Goblin 2 Scimitar Attack against Valar: 5 Damage: 7 Slashing

Goblin 3 Shortbow Attack against Valar: 12 Damage: 7 Piercing

Goblin 4 Shortbow Attack against Thelanis: 16 Damage: 7 Piercing

Worg 1 Bite Attack against Thelanis: 17 Damage: 11 Piercing, on a hit Thelanis must succeed on a DC 13 Strength saving throw or be knocked prone.

Thelanis, Valar, and Amiz are up. You have one worg and two glowing goblins attacking you. While another worg snaps at their heels, and Gark and his two goblin friends pepper you with projectiles.

Thelanis uses her dark powers to curse one of the glowing goblins, then stands and attacks with her longsword.

Bonus:  Hex on glowing goblin.
Action: Longsword on GG: Attack: 18 Damage: 17

One goblin drops to the floor dead.

Amiz and Valar are up, with that goblin down, you now face down one glowing goblin and two worgs. Gark and his bow goblins are still at the back of the room but you'd be open to opportunity attacks from the others if you ran for them.

Valar attacks: 8 damage: 11

Valar, feeling crowded by the oncoming enemies, can't properly wield his sword and is blocked by a snarling goblin. 

Amiz attacks the goblin attacking him.

Attack: 17 Damage: 10

And the other glowing goblin goes down.

Draíocht is up. You have two worgs fighting Amiz and Thelanis, if you wanted to, you could run past them without occurring an opportunity attack, and get to the back of the room with Gark and the two other goblins. Liarona is on the floor keeping down as asked, but she gives you a look as though she would back you up if asked. 

Draíocht, remembering the excessive brutality the worg riders has presumably visited upon the dire wolf they found, will choose to go at the worgs to help his fellow party members clear a path. He snaps his jaw as he prepares to bite.

Movement: To the worgs.
Action: Attack a worg.

To-Hit: max(8,3) + 5 = 13 (advantage from pack tactics of Dire Wolf as the worgs are by the others)
Damage: 2+6+3 = 11

[[
Customized an automatic pistol to get it working in the character sheet. Will be putting other weapons I customize in the "Wildshape Attacks Management" pouch I added to his inventory. Will probably use custom actions in cases where it's not as easy to get the damage type and dice right.
]]

Oh cool.

Draíocht takes a bite out of the worg's side, it turns on him as the other bites at Amiz.

Gark yells at the other two goblin's, "Get in there you fools! Kill them now! for Lord g'Ruek!" The two goblin's rush forward as Gark throws another javelin.

Worg 1 Bite against Amiz Attack: 9 Damage: 9 Piercing and on a hit, Amiz must succeed on a DC 13 Strength saving throw or be knocked prone.

Worg 2 Bite against Draíocht Attack: 19 Damage: 10 Piercing and on a hit, Draíocht must succeed on a DC 13 Strength saving throw or be knocked prone.

Goblin 1 Scimitar against Valar Attack: 17 Damage: 3 Slashing.

Goblin 2 Scimitar against Thelanis Attack: 9 Damage: 5 Slashing.

Gark Javelin against Thelanis: Attack: 12 Damage: 6 Piercing.

Thelanis, Amiz, and Valar are up. Two goblins and two worgs are battling you as Gark stands in the corner throwing javelins.

Draíoch STR saving throw: 8+3 = 11
so knocked prone

I believe both the affected by FF goblins are dead, but just in case there's something I'm forgetting.
CON Saving throw for concentration: 12+2 = 14

Yeah that's right, they are both dead.

Thelanis pulls the black aura off of the downed goblin and onto the live one attacking her.  She slashes out with her blade.

Bonus: Move Hex.
Action: Longsword: Attack: 16 Damage: 13

Another goblin goes down, They drop quite easily it seems. Gark let's out a big grunt, and picks up his morningstar and moves to start making his way towards you.

Amiz and Valar are up.

Valar attacks: 18; Damage: 15

The worg that Draíocht is fighting goes down as Valar rams his sword into its back.

Amiz is up, you are in melee with a worg, while Gark is lumbering toward you with malice in his eyes and a morningstar in his hand.

Amiz attacks the worg with his axe:

Attack: 21 Damage: 12 Slashing

The worg bites at Amiz, while Gark rumbles forward and strikes at Draíocht with his morningstar. "Eat the dirt you elf scum!"

Worg Bite against Amiz Attack: 20 Damage: 9 Piercing and on a hit, Amiz must succeed on a DC 13 Strength saving throw or be knocked prone.

Gark Morningstar against Draíocht Attack: 7 Damage: 8 Piercing.

You all are up, Amiz is fighting a Worg, while Draíocht battles the raging bugbear Gark.

[[Are there any adjacent allies to Gark. Wondering if would get Pack Tactics advantage. Or if there's any enemies where that would apply within reach (so as to provoke opportunity attack from Gark. ]]

Edit: Draíocht was also knocked prone by the worg. So wouldn't Gark's morningstar attack have had advantage against him? (I'm assuming he has within in 5ft though, so I might be wrong.)

Thanks for your honesty. Here’s Gark’s advantage roll:

7

And yes you could get Pack Tactics with Thelanis near the bugbear.

Draíocht snarls as he dodges the bugbear's morningstar. He gets back up and snaps back at Gark.

Movement: 25ft to stand up from prone.

To-Hit: max(15,5) + 5 = 20
Damage: 5+3+3 = 11 piercing

On a hit, Gark must make a DC 13 STR saving throw or be knocked prone.
