He will throw the body of the guard to the side and skitter toward the other guard.

Same multiattack:

1st claw Attack: 23 Damage: 6(if hits target is grappled)

2nd clawAttack: 7 Damage: 10

Sting Attack: 10 Damage: 11

(if sting hits he needs a CON save DC 12 23 poison damage on fail, half damage on success)

You hit the guard with one claw, grabbing it. Lorzire, your up

Iorzire sees the second guard is done for and looks for the nearest other person, not realizing his blunder.  

He yells at them, saying, “Stop where you are; I believe a friend of mine wants your soul!” and uses Intimidating Presence (They must make a WIS save of 13 or be frightened until next turn)  He then runs to the person and makes an attack, if close enough.

Hit: 27 Damage: 11

You kill them. The people are running away now, you seem to have terrified all of them

the guard makes a strength throw to get free of the grapple:

18

Shadow shrugs his shoulders,

”Actually I’m satiated for now. But I gotta be honest, even I am a bit distressed to be asked to kill literally everyone.”

Roth

"Ahem, perhaps he meant 'everyone in the contest'...at least, that's how I understood it."

The Wild will click his pincers in the direction of the running people then turn toward the group.

Roth will continue to check the bodies of the opposing team...

They have roughly 200 gold all told, Brock had a greataxe, the human fighter had plate mail and a greatsword, and both wizards had only quarter staffs.

Roth

Roth will split up the gold, "We should find a place to stay for the night...maybe we won't be so welcome here.  Maybe there is more danger than these weak townguard, and certainly we should be ready to destroy any other teams.  I would suggest an Inn in another part of town."

Roth is also going to grab the corpse of the fighter and throw him over his shoulder.  "The Storm Lord respects strength and power, and this armor will give me more." noting the platemail the fighter is wearing  "I need to strip it off, but not out here...let's move.  I'm not sure if any of their other  items were magic.... "

Shadow slinks ahead, trying to be stealthy while also trying to spy out other possible adventuring groups

Stealth if needed 23

Roth will stay some distance behind Shadow, at least 30 feet as there is no way he is going to stealth his way around in chain mail and carrying the fighter's corpse.

The Wild will stay a ways back behind the rest of the party following in his giant scorpion form, keeping and eye out for trouble

Iorzire will stay with Roth, and make a comment, “Sorry... I’m not very smart.  I’ll try to stay out of your way next time...”
