Galingal moves forward quickly, checking on the status of both of the attacking duergars. Then he checks whether the target of their attack is alive or not as well.

(Oh, was it just the one left? Oops. XD

But oh well, best to keep it as this, just in case he happened to have some invisible friends close by)

Petmailer rushes forward in sync with Galingal to check the bodies, also to check on the man who was attacked, listening and watching to detect anyone who may be hidden.

Stena blinks as she watches the group get involved, which is exactly what she didn't want. She looks mildly more annoyed, but not really all that much.They were charging them, so they did need to be put down.

Stena doesn't approach the scene and instead surveys the area for more interested parties/bystanders.

Perception: 18

It is clear as you both approach the end of the dock that one of the attackers is dead, the other collapsed under whatever spell Kolose cast, but with the face masked and hooded, it's hard to gauge.

((One of you checking on the target of the attack can give me a Medicine check. Investigation to search one of the three (specify who).))

Galingal does his best to stop the bleeding of the victim of the attack, though field dressing and first aid was never a strength of his (Medicine 11).

He looks over at the sleeping attacker and says “We should finish this one before he turns invisible and gets away.”

Petmailer slings his bow over his back, he puts his hand on his short sword hilt and bends down, pulling the mask off the duergar, assessing whether alive or dead or playing possum.  He looks to Galingal saying, “Should we end him before he runs away to fight again?  How does the merchant look?”. He quickly searches the duergar.  

Investigation : 17

The merchant is dead, as Galingal moves to staunch the flow of blood, he realizes that it's already slowed of its own accord, with no heart still pumping it through the man.

The first assassin is calos clearly dead, an arrow protruding from the torso of the body. Petmailer takes a few moments and searches the still living one, who giggles a bit and mutters something in dwarven before going back to snoring as the drow's fingers explore his body looking for hidden valuables or clues.

The duergar assailant is clad in dark leather armor, with a hooded cloak and a neck wrap that was pulled up over the lower part of his face when he attacked. With it down, the sleeping fellow is on the younger side of middle age, a scar creasing one cheek down into his beard. The glowing sword is nowhere to be seen, and it doesn't seem that he brought much in the way of personal effects with him on the job, not so much as a coin pouch to be looted. What Petmailer does find is a folded sheet of fish-skin parchment, with a charcoal sketch of what is clearly the merchant lying dead on the docks in front of you.

Stena hangs back with her other 'friends', Jimjar remarking to the goblins, "Five gold says the dead guy was our contact."

"Woah, you think so, bruh? That'd be gnarly."

"Totally gnarly."

Galingal looks around at the group then stands and starts heading back the way they came, away from the docks.

"Duergar kill duergar but when guards come, all non duergar get rounded up," Galingal says. "We should not be here when guards here."

Quickly, Petmailer looks over at Galingal to say, "Should we leave him alive?  He is clearly an assassin.  But I agree with you, we should run."

Kolose

"We shouldn't kill him if he's our only source of clues, right?" Kolose says, seeming hesitant to just kill an unsuspecting man, even if he very quickly adds.

"But we either have to get out real quick or do something, he's about to wake up."

“Fine.”  Petmailer takes the folded skin of parchment paper and runs back to the others, getting away from the scene before the duergar wakes up.   He is moving at maximal speed, giving the parchment to Stena or Kolose to examine when he gets within arms reach.  

((Is the plan to flee at all haste? What direction? Coming from the docks, if you bear leftish, it'll return you to the Blade Bazaar, if you turn sharp either right or left you'll continue along the edge of the Darklake, while bearing rightish will take you deeper into the district in a portion you've not explored yet. To the distance on your right is what may be a tavern (based on the silhouettes of patrons and faint sounds of revelry echoing over the water) of some sort jutting up from a low island, connected to the shore by a long pier, both the pier and the structure better lit than the largely empty docks you are on now.))

Stena ignores the gnome and goblin banter and keeps her eyes on the paths to the dock.

She looks down at the paper thrust into her hands by Petmailer and opens it to look at the face shaking her head she asks,

"Who is this? Why would ye grab it?"

She will indicate they head back to the Bazaar.

With no time to debate, Galingal moves along with Stena towards the Bazaar.

"Should find inn after clear," Galingal says as they move.
