The Hand of Yurtrus is still up, but looking very beat now.

Erix moves in with Clumulk to get behind the orcs (Brutal Charge so no opportunity attacks) While Clumulk attacks the most left Orc

Clumulk: to hit: 8
The last Boar standing gets 11 temp hp back and attacks the 2nd Orc from the left: to hit 21 for 5dmg
Erix goes for the Orc on the right trying to pull it towards them: to hit: 13 for 8dmg

LANDMOP will cast Ray of Sickness at 2nd level on the Hand

Attack: 19 Damage: 12

Mark takes a shot at the Blade of Ilneval, doing 19 damage as the bolt sinks into the Blade's side. Erix and Clumulk plunge into the Orcish ranks, biting and whipping around. LANDMOP's Ray finally drops the Hand of Yurtrus, the Silence drops. The Blade of Ilneval would look worried, and perhaps give the order to retreat, if he wasn't stunned from Zoveldra's blows. The Orcs fight on, not realizing the tide of battle has turned in their bloodlust.

Orc 1 Axe against Boar Attack: 9 Damage: 11 Slashing

Orc 2 Axe against Boar Attack: 21 Damage: 11 Slashing

Orc 4 Axe against Clumulk Attack: 10 Damage: 8 Slashing

You all are up. On Zoveldra's turn, the Blade of Ilneval recovers from the Stun.

LANDMOP gains 6 temp HP from Grim Harvest, turns her Shadow Tendrils on the Blade. 

Attack: 21 Damage: 3

That strike kills the Blade of Ilneval. This the other Orcs do notice, and look at each other worriedly. Elero, Erix, Mome, Mark, and Zoveldra are still up.

Elero takes a shot at the most injured remaining orc.

Light crossbow attack: 19 to hit and 9 damage.

The Protector Cannon will pulse out 11 temp HP for the Boar.

That's just enough to drop Orc 4. Only two Orcs left, Erix, Mome, Mark, and Zoveldra are still up.

The boar gets hit good, however the protective energy of the cannon protects his own skin. After which he feels the protective energy back up again he attacks  Orc1:

to hit 23(CRIT) for 4dmg.
Clumulk also tries to take a bite out of the Orc going into a rampage (target is prone if hit)

To hit: 23 for 5dmg
Erix meanwhile keeps using his Thorn whip, thinking the battle is almost won:

To hit 10 for 4dmg.

Mome attacks the nearest orc with her trident (attack 18, damage 3, topple)

Zoveldra goes after the orc Mome has toppled, moving on to the others if necessary.

Action: Unarmed Strike to hit with advantage 25, damage 8

Extra attack: Unarmed Strike to hit 16, damage 6

Bonus Action: Unarmed Strike to hit 11, damage 13

And with the last few blows from Zoveldra, Mome, and Erix, all the Orc warband are defeated. You stand in the cavern, the large stone doors now open, with the dead Orcish warband littered around you. What's the next move?

"...and that, in a nutshell, is how the Warforged were created," Elero says as Silence drops.  Then he looks around awkwardly, and asks if anyone needs shielding from the Protector Cannon, or healing in general.

Zoveldra shakes her head, still feeling fine. She will begin looking for any clues or items of use on the bodies.

Perception: 22

"...and that, in a nutshell, is how the Warforged were created," Elero says as Silence drops.  Then he looks around awkwardly, and asks if anyone needs shielding from the Protector Cannon, or healing in general.

 

 "I am in need of repair." LANDMOP says. Looking at all the littered corpses, frustrated to let them go to waste, but not having a spell slot to animate any

Erix will help Zoveldra asking

"Where there more Orcs with Anric? Or where is he?"

"We haven't actually seen him, but that necromancer and her friends said they sold him to these orcs. There must be more, likely many."

"Ah, I can help." Elero approaches the Warforged, with the Protector Cannon dutifully following.  After a quick examination of LANDMOP's remarkable physiology, he changes his mind, opting for Cure Wounds rather than Mending, and casts it at first level, healing 10 HP of damage.

The Cannon also pulses out another shield burst, giving LANDMOP 7 temp HP on top of the healing.

Mome also offers to assist with healing, if any more is needed. "The silence spell really forced me to rely on my not-so-trusty trident." She does this while checking the bodies for loot. She is happy to add pouches of coins and maybe a weapon or two to her collection. 

"wait, you wanted to go inside without knowing what you were up against?" Erix says with a raised eyebrow.
