Graelor rolls a (12,13) + 1 for a 14 initiative.

Eggo Lass Initiative: 2+3 = 5

"THE BELL?!" Salamander shouts. He jumps up in the air a little bit, waving his arms around. The flame in his hand extinguishes. He growls. "No one makes a fish out of my son!"

((Initiative: 6 + 2 = 8))

[I'll wait for Sly's initiative, then take the average of all of yours compared to the orcs to work out who goes first. I'll find an easier method in future like the average Dex score or something]

[I also wouldn't mind if you immediately roll for me if that speeds things up. It's not like initiative will be modified in most cases.]

Sly saw this coming and raises her staff defensively, ready for a confrontation: Initiative 14  [ignore newest roll in the campaign log, the older one counts]

Orcs: 13

[I don't need to do the maths to work out who goes first lol]

The orcs all go to attack, each moving about the room to apprehend the nearest player, malicious delight across each of their faces, whilst the eye-adorned orc in the corner mutters an incantation

Orc 1 will attack Salamander Pie with a Greataxe: 22 to hit, 12 slashing damage on a hit.
Orc 2 will throw a javelin at Eggo Lass:  7 to hit, 8 piercing damage on a hit.
Orc 3 will throw a javelin at Sly:  22 to hit, 4 piercing damage on a hit.
Orc 4 will attack Graelor with a Greataxe:  14 to hit, 11 slashing damage on a hit.
Orc 5 will throw a javelin at Graelor: 22 to hit, 4 piercing damage on a hit.
Orc 6 will throw a javelin at Salamander Pie: 18 to hit, 5 piercing damage on a hit.
Orc 7 (Eye): Will cast command on Sly and tells her to 'approach' (Make a DC 11 Wisdom Saving throw or Sly has to spend her next turn moving towards the orc by the shortest and most direct route, ending her turn if she moves within 5 feet of orc.)

[This is gonna be a tough battle, good luck all, let's hope Rhino gets back online soon XD]

I understand that Graelor gets hit for 4 points of damage. 

Graelor shifts his mace from his right hand to his shield left hand. He speaks a few words and makes a gesture with his hand and casts SPIRITUAL WEAPON and directs it to attack Orc 4. I rolled to hit 11 and damage 7. As a bonus action, I direct the SPIRITUAL WEAPON to hit Orc 4 again. I rolled a 22 and damage 11.

If you will allow one additional action, I will pull the javelin out of me.

[Yep, 4 points of damage is correct. If you haven't already, make sure you've removed those hit points from your character sheet, just to keep track of things. Also, removing a Javelin as a free action is totally fine]

Your spiritual weapon misses Orc 4, and he cackles as it flies past him, but then he gives a deep gasp as it then pivots round to slice through his stomach from behind. The wound does not immediately kill him, but he is bloodied.

"I! Will! Mess! You! Up!" Salamander Pie takes to blowing a note on each one. Somehow he managed to get his birdpipes out during the start of the altercation. Unfortunately that act meant that as soon as he blew the last note he was suddenly slashed in the face with a greataxe. Putting his hand to his face he is surprised it didn't kill him. His head rings like as if he were the bell. He doubles down. Both hands soaked with his blood. "Hruh?"

He doesn't have much time to contemplate. A javelin is thrown at him and he is completely winded. It pierces through his lungs. He can't even gasp.

((He is currently at 18 - 12 - 5 = 1 HP so 1/18 HP))

Looking around with cloudy eyes he goes for his best shot. Goblin man is reduced to squeaks and whiskers. He turns into a swarm of rats. He starts scurrying.

((Action: Wildshape into swarm of rats ))

((Bonus Action: Hide but I got a got 2 + 2 = 4 so not hidden))

((I'm gonna say that the Hawk Spirit was already in the middle of the orcs in a 30ft radius. He uses his Reaction to give advantage to everyone attacking within that radius. ))

[Yeesh, Salamander's getting hit rough. I'll cry if he dies so early on]

((AHHHH :( noooo same))

Eggo Lass brushes off the javelin that passes by her but the orc's legalese still smarts her. She shouts with force, "The Common People's Land Decree is overruled by the 623 Writ of Lolth, 4th Edition! Any territory within the Underdark claimed by Drow is and remains Drow regardless of the some bloody archivist interloper!" She waves her wand and lets out a blast of force.

Spray of Cards
Damage: 1+9 = 10 force damage, 15ft cone
DEX Save DC 14
On success half damage
On fail, full damage and blinded until the end of their next turn

Sly winces as the javelin scrapes past her shoulder. These orcs were clearly not to be reasoned with.

The wizard is about to cast a spell, but her mind is not her own anymore [wisdom save: 4]. She approaches orc 7, ending her turn close to him. Assuming that the orc is within 30 feet, that should work.

[Welp, rip Sly]

Eggo Lass's Spray Of Cards manages to hit Orc 4 and Orc 5 in the middle of the room, however Orc 4 doesn't need to make a save as even if he succeeded, the flurry of cards would still be enough to tear through his flesh and kill him. 

Dex Save for Orc 5: 4

[Sorry for the late response, I was trying to find a way to number the Orcs on the map to show who's who, but basically because of the ways the layers work on the software I'm using, I can't put text on them, so instead I've put coloured dots on each of them. They are numbered from left to right, top to bottom, with the only change being that the Eye has moved to match the numbering system (that shouldn't disturb any flow of combat, it's just a change in where they and Sly now are) They are as follows:

Orc 1 (White)
Orc 2 (Yellow)
Orc 3 (Green)
Orc 5 (Black)
Orc 6 (Blue)
Orc 7 (Eye - Fuchsia) 

Feel free to refer to them by colour or number when determining which one you're attacking, sorry if I made things complicated, this is my first time running group combat over maps on PbP, so I'm still learning!]

Angered by the loss of their fallen comrade, the orcs go to attack again, and seeing that Graelor dealt a significant amount of damage on the last turn without suffering too heavy wounds, they target him more than they usually would, focussing on ranged attacks as they don't have the space to crowd in closer. They also ignore Salamander Pie for now, since he's a Swarm Of Rats that aren't as fun or easy to kill. The Eye Of Gruumsh, even though they lured Sly in, is distracted and frankly annoyed by Eggo Lass's comment and effective attack, so decides to bolster their troops in case she uses such a spell again rather than attacking. Orc 5, however, has been severly wounded by Eggo Lass's spell; he is covered in paper cuts and has a card covering his eyes so he can't see. 

Orc 1 (White): Attacks Graelor with a Javelin: 18 to hit, 5 piercing damage on a hit. 
Orc 2 (Yellow): Attacks Graelor with a Javelin: 8 to hit, 6 piercing damage on a hit. 
Orc 3 (Green): Attacks Graelor with a Greataxe: 10 to hit, 12 slashing damage on a hit. 
Orc 5 (Black) -10 (Blinded for this turn): Attacks Sly with a Javelin, with disadvantage: 7 to hit, 8 piercing damage on a hit. 
Orc 6 (Blue):  Attacks Eggo Lass with a Javelin: 21 to hit, 8 piercing damage on a hit. 
Orc 7 (Eye - Fuchsia): Casts Resistance on Orc 6 (Blue). For 1 minute they can add 1d4 to one saving throw of their choice.

Everyone is now back up in initative!

Fearing the worst, Graelor braces for the next round of attacks. After dodging 2 javelins, and deflecting a vicious axe attack from an Orc that has pressed in on him, Graelor feels emboldened and mutters a prayer of thanks to Helm. “NOW, FEEL HELM’s WRATH, ORC!! Graelor yells and casts INFLICT WOUNDS on Orc #3. I rolled 15 TO HIT and 20 points of damage.
Graelor’s spell causes his hand to glow white and with a quick well placed touch to the Orc’s face, the light transfers to the Orc and spreads across his body leaving a spreading black lesion as the Orcs flesh dies on it’s bones. 
Knowing that the Orc is done for, Graelor sends his Spiritual Mace flying at Orc 2, in response to his javelin attack. Unfortunately, Graelor loses his concentration and the mace misses wildly. I rolled a Natural 1 to hit.
Seeing the success of the last spell, Graelor looks at the Orcs with his raised bare hand, and with a wicked smile, starts to noticeably chant something.

Orc 3 practically evaporates, and the Orcs are all now even more terrified of Graelor.

Sly, Eggo Lass and Salamander Pie are all up!

Sly feels like it's decidedly too crowded where she is, in the middle of the orc horde.

One of them strikes at her with a jab, but the wizard stumbles out of the way, occupied with a spell that would create her some desperately needed breathing room. The tiefling disappears in a cloud of wispy smoke and reappears outside the room, 30 feet from where she departed.

She targets orc 5, as he seems wounded. Weaving necromantic energies, she tries to take away what was left. Her words echo in his ears: "I'm afraid the present conditions are not conductive to your survival." [Wis Save 13 or take 5 necrotic].

Eggo Lass revels in Graelor's prowess and the way the orcs fall like wheat before the scythe. She enters a happy place and begins to sing in Elvish as she fights. ♫ Seven little orky boys chopping up some sticks, one chopped himself in halves and then there were six. Six little orky boys playing with a hive. A bumblebee stung one and then there were five. ♪

[[ I read Agatha Chrisitie's And Then There Were None back in school and the poem has stayed in my head. ]]

She unleashes a bolt of magic at Orc 5, hoping to finish the job.
