"I am aspiring to lead this bunch but Klarg, the boss, is in my way. Bring me his head and i'll consider letting you and this one go"
 
The goblins in the cave have positioned themself advantagiously making it clear that they are ready to resume battle at a moments notice.

Whisper turns to his companions. "I do not enjoy leaving Sildar in the hands of these goblins, but I do not believe we have any other choice."

SAKARIA

"Yes, you're right Whisper" says Sakaria, "Let's quickly find this Klarg and save Mister Hallwinter, even if I don't like coming to terms with this kind of creatures".

Gritting his teeth, Kylar is loathed to be in such a situation.

"Damnit... There doesn't seem to be a better alternative then."

"We agree to your demands." Whisper says. "But first we wish to know the whereabouts of one Gundren Rockseeker, a dwarf who was traveling with Sildar Hallwinter, your current prisoner."

"I do not know the whereabouts of this stinky dwarf, Klarg sent him away as soon as he arrived. but no more delay go kill KLarg immediatly if you don't want his one here to suffer"

"You can find down this path" he points along the path you climbed on through the slope. "follow it across the bridge and tell my guard you are sent by me, you will find Klarg at his lair behind the cave of pools"

"can't miss it"

With a look of helplessness Whisper starts down the path.

Harry follows behind Whisper and says in a low voice, "I've got a bad feeling about all this. How do we know that goblin is going to keep it's end of the deal."

"We don't" Whisper replies. " In fact, he probably won't. But anything is better than watching our friend executed before our eyes. "

SAKARIA

"I agree" says Sakaria, "Let's quickly find this Klarg, deal with him, and hope that foul goblinoid will keep his word. We don't have any alternative, sadly."

Kylar follows the group, clutching the hilt of his sword as he walks away from the goblins.

"What sickening cowards, hiding behind hostages... That's low. No. That is beyond low. They will pay for this."

Kylar rants, quite furious.

After a couple ft you come across a sleeping goblin who's supposed to guard a bridge crossing the river around 20ft above the stream you followed earlier.
With no need to talk to him you simply walk past him and you see a shimmer before you?
Two more goblins sit around a campfire in this room currently cooking, or at least the hold some sort of eatible into the fire.
Opposite of you you see a second cave entrance leading into another room where you can spot more creatures but not exactly what kind of

Kylar watches Whisper, following his lead.

Whisper keeps his voice as low as possible. "We need to capture one of them. Hopefully it will lead us to Klarg."

SAKARIA

"I don't think they care as much for one another as to care if we capture one of them. We'll have to fight no matter what" says the tiefling in a low voice.

" To battle again, friends. " Whisper says, casting Frostbite on one of the goblins.
