Zanigur Dexterity (Stealth) check: 18

Grimm has no plans on sneaking in with the group. Instead, she'll position her self about ninety feet away from the ambush point so she could reach them with some support spells or the like after moving in closer. 

Stealth: 8

 Oh man, averages just barely got you guys by! Good thing Urag was there to be your distraction.

Kara and Grimm remain about 90' back, taking cover behind a small copse of nearby trees as Urag gives the group one last look and a nod before taking off at a limping dash toward the thickets! As Urag disappears behind the bend of the thicket Zanigur, Irena, and Puck begin creeping up towards the hillside and the hidden area behind the thick wall of thorns. You all here a loud commotion as Urag begins talking loudly and trying to distract the two goblins on guard. It turns out, luckily for the group, that they had Urag with them... as both Irena and Zanigur splash quite loudly while crossing the stream; however, the three are able to sneak up behind the two goblin guards. Urag is kneeling in the corner speaking rapidly and gesturing wildly towards his injured leg while the two goblins (red and blue) have their backs to you and are gibbering back in the goblin tongue. 

Irena, you hear that the guards are asking Urag what happened and if he was followed to which Urag replies loudly that no one followed him. Zanigur, Irena, and Puck please check the map for positioning. Let me know if where I placed your icon is okay and if not, feel free to move your PC around or let me know where you'd rather be if you cannot edit the map. Once everything looks good, feel free to take your Round 1 combat actions as you have successfully Surprised the guards.

Zanigur hefts the crude goblin bow and nocks an arrow, aiming for the goblin on his right as the other two sneak up for the attack...and at the opportune moment....

Shortbow Attack: 22 Damage: 4 piercing 

The twang of the bowstring resonates with bardic energy and carries a strange tone that seems to inspire his allies. (Bardic Inspiration to Puck, as a bonus action) 

Puck moves within 20 ft and tosses his dagger at the same goblin Zanigur targeted.

Ranged Dagger Attack: 24; Piercing damage: 5

Puck considers inspiring his rogue friend Irena, but knowing they are attacking from the shadows, figures she has a very good chance of landing her shot anyway without his help, and hopes to conserve his limited resources. 

Irena thrusts her rapier at the red goblin,  Attack: 20 Damage: 10.

With Urag's aid, several members of the party sneak up behind the two goblin guards and flawlessly dispatch them! Zanigur's arrow punctures the shoulder of one of the goblins, just as Puck's dagger soars through the air and embeds itself deep into the creature's throat, severing the carotid artery. Meanwhile Irena stabs her rapier down through the ribs and straight into the heart of the other goblin. Both hit the ground simultaneously with slight thumps and no more sound... Urag swallows hard as he stares at his fallen comrades and looks very conflicted, but says nothing as he watches you all warily.

Zanigur, please make a Perception check.

Zanigur Perception 9

If there is no imminent danger, Zanigur will enlist the aid of Urag, Puck, and/or Irena in moving the goblin bodies out of sight. 

Seeing everyone relax some, Grimm nods at Kara and begins walking towards the group to help them hide the grisly results. 

“Not sure what we’ll find in there. Any ideas, my merry friends? And Urag, once we get in the cave, which way to where they keep prisoners?” Zanigur asks the goblin as they are heaving the bodies into the brush. 

Kara rejoins with the others. She has no reason to distrust the party currently, and so doesn't actively check for evidence of wrongdoing. "A shame I was not able to help. Onwards to the cave, I would say?" She gestures at the cave mouth as she slowly makes an approach. She listens carefully, trying to hear anything other than the babbling brook.

Perception: 13

Grimm replies, "They'll need our help soon enough. Sure, they're efficient against a couple of guards we have the drop on, but we won't have that luxury in the cave."

"Is anyone stealthy and can see in the dark?  I'd take point but as sharp as my eyes are, I'm afraid they need light."

"Puck of the Shimmering Summit at your service, Miss Irena"

Puck points a claw to one of his cat-like eyes.

"Also feelin pretty confident thanks to Zanigur. Happy to take a peek and report back. Just, ya know, stay close. And if you hear a shout, come runnin."

Stealth Check: 18 + Inspiration: 2

Thankfully the rush of the stream through the caverns and the numerous natural falls mask the sounds of the group speaking and tossing the dead goblins into the thickets. Neither Zanigur nor Kara can hear anything from the cavern entrance over the echoing rush off the swirling, cool water. Urag steadfastly refuses to help conceal the dead goblins. "No! Me help you get to cave. Me part done. You let Urag go now." He looks at the drag marks from the blood and swallows. "Human prisoner in our sleep, eat place across bridge. Go up to water place take bridge. Urag go now, never come back." He starts to move towards the opening in the thicket, unless someone stops him he will cross the stream and take off quickly towards the trail at a limping gait.

Puck looks around at his other companions and shrugs, indicating his indifference about whether Urag stays or leaves. 

Grimm ignores the escaping goblin. 

"So," she says, "let's go in. Those who can't see are the torch bearers - best if they stay towards the middle."

“I agree with Irena,” says Zanigur. “No torches, at least for now. Let’s go with stealth and see what we’re dealing with first.”
