Maybe they're trying to kill him. They might've cut out his tongue as punishment or torture but he escaped and now they're back to finish the job. 

Anyways, I suggest we head for the armor and weapons room to fully suit up before we continue.

“I agree we should stick close. Maybe we get off this ship!” Fulqrim glances around nervously at the group.

The armory is probably somewhere on the third floor. Let's head up to the second floor and see what we find. Vayu heads for the stairs and begins ascending.

"Whatever we do, let us do it quickly and begone from this ship. I do not want to see the inside of another cell. I will follow your leads."

As you all creep up the stairs, the notice two from before are walking down the 2nd level's corridor. A few halfings in black clothing walk between the room, all of them are carrying knives, some bloodied, some clean. The two from before stop at the large room at the end of the hall looking to another group of similar people. They are about 60 feet away from you all. You all are at the stairs. The hallway is about 10 feet wide and have 8 doors leading to the crew rooms. 

 (How many do we see?) Nate looks about, then says to the group, "Alright, decision time. Are we fighting our way out, or are we sneaking our way out? Because we could wait here 'til they go above deck, or we could try battering ram-style. What's the play?"

(4 halflings walking the hallway, the large room has more people you see but can't tell how many.)

"Perhaps this is our way out? These do not look like Aerovail military. Maybe we could link up with them to escape?"

"Convince them to join up?" Liana strokes the chin of her mask, "I like our odds on that. Unless Aerovail has created a small assassin platoon while I wasn't looking."

The enemy of my enemy is my friend... I like that. Vayu turns to the group, if that is our decision then let's proceed.

Vayu comes out from where he is hiding, Hello, I see you're not Aerovail guard like me. I'm trying to escape, care to help? I could help you if you need anything...

Here's a persuasion roll if you need it.

Nate stays hidden while Vayu just pops out of nowhere in front of a dozen armed men.

"...We got a straggler here." A halfling says, as he calls the others over to him. "Don't look like one of the soldiers." Says another halfling, "Could be lying, just threw on some other armor to fool us." Another one says, "Alright, alright...one of you go tell the others we got someone here." The one that took charge holds his knife out, "Now listen here, we got a someone going to get the first mate here to check you out. Now no sudden moves, we see anything suspicious, we'll throw you out the hole below." You see one of the halflings go off to the larger group in the common room.

Sure thing, I guarantee you the first mate will tell you I'm a criminal. I'm not sure how much he knows about me but I was part of the infamous Blue Bastion's crew alongside with Captain Bennet Skriver. He says hoping to ease the already tense atmosphere.

Also you can put the dagger down, there's no need for it, I'll follow without complaint. Vayu continues.

Here, take my scimitars, when you find out I really am who I say I am you can give them back. When he finishes saying this last part he'll set his scimitars on the ground and take a few steps back.

Another persuasion roll.

Fulqrim watches nervously from afar. He tries to get closer while staying quiet and hidden. He wants to be ready in case things go badly.

Stealth: 27

There seems to be a pause, the halflings stare at Vayu for a while before another one dashes off into a room. The two halflings close in on Vayu, "Sorry then mate, can't have other pirates know what we're doing." The one that dashed off comes back with a rope. "Now we're gonna tie you up now, and ditch you on a lifepod. Or we cut your throat." They raise their daggers, preparing for a fight, the one with the rope just stretches out the rope a bit. 

Attack: 10 Damage: 9

Lilliana hears this and immediately extends her hand to send out another blast of the eldritch blue energy towards the the closest halfling with a dagger!

Seeing Lilliana attack, Nate mutters, "****," and hits the halfling with his swords.

Rapier Attack 24 Damage 11

Scimitar Attack 21 Damage 8

With that Vayu will use levitate (racial ability) on the hafling holding the rope and use his full movement to grab his scimitars and then back up as far as possible.

The hafling needs to make a DC con save of 14 or higher.

(Surprised)

A halfling yells out as the eldritch enerygy scorches across their chest. It still stands as it pats out the remaining magical embers. The other one with his blade out looks to his companion only to feel the piercing of the rapier go into his chest. As he tries to retract himself from the blade, he finds himself met with the scimitar across his throat. The last halfling there rises to the ceiling of the deck, dropping the rope. As a few halflings still stand, they shout to the group ahead. "We got trouble back here!"

(Accidently left the editing part on last post.)

(Roll for initiative, the first round is all you guys since they're surprised.)
