The roar, despite it's weakness, and the manouvering of the ballista was enough to make the two guards instinctively draw their weapons. Several nearby Warriors did the same thing.

"Drop the bow, Fomorii!" the blonde one yelped, his axe held high, ready to bring it down in a moments notice.
"Ballista" the bearded one corrected, his own scimitar held in a more defensive posture. Then, in a more soothing tone he said "We do not wish to fight you. This is your only chance to walk away - alive. If we fight, one of us won't. Ask yourself, friend - will the gods smile on me today?"

The commotion caught the Captains attention. He rushed over to the standoff, his short captain's cloak blowing impressively behind him. Whilst he had never met any of the Fomorii, part of his training was a negotiator. Now seemed like the right time to practice those skills.
"Stand down, lads! Sheathe your weapons!"
The guards did so, however slowly and reluctantly.
"Fomorii" the captain adressed the enraged Nephilim directly "Weapon. Down"
To illustrate his point, the captain removed his scabbard from his hip and put in on the ground, then stepped away from it.
One of the guards tried to protest, but was swiftly silenced by his fellow soldiers. Their eyes turned to the snarling devil, awaiting it's next move.

"I'm not going to hurt you" the guard with the Succubus reassured, swiftly sheathing his scimitar. She was in a bad way, and needed help. Fast.
Thinking about the injury on her abdomen, he pulled his flask from his hip. He was no healer, but he knew that open wounds needed to be cleansed - there was no point in fixing the poor girl up for her to succumb to disease later.
The soldier acted quickly. Tearing a strand of cloth from his sleeve, he opened the flask and poured the water onto the wound. When about half the flask was used, he handed the rest to the Succubus and signalled her to drink. Then, he started wrapping the makeshift cloth around the gash, praying it would do until they got to a proper healer.

"It's okay. I'm not going to hurt you"
The female soldier ignored the calls of the Nephilim or the yelling of the other guards. Instead, she offered her hand to the cowering demon, with compassion in her eyes and a smile on her lips. She looked genuinely warm and friendly, with little malice about her.
