"Might want to ask why did we get ambushed in the first place." Eniallis suggests while translating what Alexander said to the goblins. (Just assume you're able to talk to goblins from here, since Eniallis translates what you say)

Wolf Blade rough house's the tied up goblin 

"I'd think their poor friends ambushed us cause its what gobbos do," Liathana mused, "They don't got much of a brain between them, but I would like to know where Rockseeker is at the very least and we know you took them!"

Liathana points her dagger at them in general. "Tell us or so help me I will cut you down right now."

Intimidation: 18

“D-Defenses?” The tied up gobling stutters “Our only defense was this p-post… We don’t build much, we’re just really smart when we’re many!” He spats, with a nervous laugh “If I can recall w-well, there were a little bit more than a dozen of us...” Trying to scratch his chin, as if thinking.

“K-Klarg is the leader, he’s a nasty bugbear that one… Well, he still receives orders from King Grol. He’s the chief of our tribe” The other one continues seems lost in thought for a bit “He rarely visits us. He doesn’t know anything about being a King. A king serves their followers, don’t them?” He complains, as he draws with his finger on the dirt “We are here… King Grol lives here, in Cragmaw Castle...” He keeps giving directions here and there, mentioning that the castle is hidden within Neverwinter Woods

“Rock-a-who?” He expresses, as the party questionarie goes on.

“The dwarf, you idiot!” The other protests, flailing his feet at the stupidity of the other, he’d hit his goblin friend with a knuckle, would he not be tied by Wolf Blade’s rope “Rockseeker, and his human friend…” He calmed down a bit, and pouted at the other “The messenger sent by the King (Grol), he told Klarg that the Black Spider wanted Rockseeker to be captured, and with him all his possessions… And something about a map too. He’s definitely in Cragmaw Castle”

“The human is still here for some reason though. He should be in our “eating cave”!” He then pats his stomach “I’m kinda hungry now...” He laughs

“Yeah… Yeemik wouldn’t let us have anything to eat until him and his group had their good share.” He groaned “He’s a bully, just because he is second in command...”

Acknowledging none of you apparently have more questions for them, they ask “Can we leave now?” One of them asks, with a frail voice “You let us go, yes?”

What you gathered from the two goblins:

• About fifteen goblins currently dwell in the lair.
• Their leader is a bugbear named Klarg. He answers to King Grol, chief of the Cragmaw tribe, who dwells in Cragmaw Castle. (Cragmaw Castle. It's about twenty miles northeast of the Cragmaw hideout, in Neverwinter Wood.)
• Klarg received a messenger goblin from King Grol a few days ago. The messenger told him that someone named the Black Spider was paying the Cragmaws to watch out for the dwarf Gundren Rockseeker, capture him, and send him and anything he was carrying back to King Grol. Klarg followed his orders. Gundren was ambushed and taken along with his personal effects, including a map.
• The dwarf and his map were delivered to King Grol, as instructed. The dwarf's human companion is being held in the "eating cave". Yeemik, the second in command, dwells there along with a small group of other goblins.

Alexander finds all of  this interesting  and highly informative. The need for haste was becoming more apparent and  the knowledge that Gundren Rockseeker was not here was disturbing. But Sildar still needed their help and they needed to act. 

"We need to get in there, Sildar needs are help. We also need to get in there and clean out the cave. Let's decide quickly on what to do with these two. We could tie them up and leave them out here or we could use them to fool are way in there. Maybe pretend to be there prisoners."

"They're too dumb to play our wardens. But I agree, we must hurry to the eating cave." Just the thought of it makes Eniallis a bit nervous.

"the four of us as prisoners to 2 goblins is a bit hard to pass off.. There dumb, but not hat dumb.. Get in, out an back on track as quickly as possible, sounds good to me" Wolf Blade agrees with while scoping out the cave entrance a bit closer 

"I think we should knock out these gobbos and leave them tied up somewhere out of our way, what say you all? We can sneak in all covert-like and make heads n' tails of what they told us."

"Agreed. These two can't just remain here flailing around. Any volunteers for two easy KOs?"

"I'll knock out this one, Wolf you take care of yours." And with that Alexander takes long sword and strikes at the base of the goblins head with the pummel. Dealing non-lethal damage. 

Attack: 22 Damage: 10  

"I've not knocked any guys out before, guess I'll try my hand at it now," Liathana admits as she bashes the hilt of her rapier against the other goblin. 

Attack: 18 Damage: 6 non-lethal, if possible.

Advantage attack: 18

Wolf Blade takes a step back for minute looking at Liathana with a slight surprised look, smiles and then uses the rope to tie the goblins legs an feet together

Trusting that the goblin before him is knocked out Alexander moves on to the other one. He sees that the others are having trouble subduing it. Using Thaumaturg Alexander makes small but harmless tremors every time his foot hits the ground, all the while advancing on the other goblin. Suddenly the goblin starts to hear ominous whispers and as it looks at Alexander it sees that his eyes suddenly go black again. It is a truly frightening sight to behold.

Speaking out to the goblin Alexander says, in infernal, " May the Nine Hells have mercy on you!" He knows that the goblin probably doesn't understand him but he hopes that the goblin understands the tone in his voice. 

Intimidation Check: 14

Even if untied at the moment, the goblin targeted by Alexander is hit and insantly knocked out. Landing limp on the ground, but breathing as well.

The other babbled as he saw his fellow goblin be dragged and tied next to him. Too altered to formulate any word, that was, until he was hit by Liathana’s rapier’s hilt.

Unfortunately, the hit hadn’t been strong enough to knock the lights out of him, and the pain managed to help him find words to curse at Liathana.
The nature of such language made Eniallis ponder if it would be a good idea to translate what the goblin had called his teammate.

Stopping in an instant with his wails and screams, the goblin’s eyes focus on the Tiefling Paladin, who no longer looked holy, quite the contrary, as his voice and appearance had taken that of a true hell-spawn.
Trembling, the goblin heard the words of warning Alexander was giving. And though he couldn’t understand any of it, once the Knight finished the sentence, the goblin’s eyes went white, as he joined his teammate on the ground.
… Would be a good idea to check his vitals before proceeding, hopefully his heart is still beating.

Once Wolf Blade finished tying the two together, the party decided to continue.

Once the goblin goes limp Alexander stops, thankful that he wasn't forced to kill the unarmed goblin. Looking over to Wolf Blade he says.

"Wolf, while you tie that one up check if it's still alive. It's felt quite the shock today. Get this one as well and once that's set let's head out." 

"Heh, at least once the tiefling blood pact is good for something. Great job, Alexander. Let's move to get to the Eating cave in time." says Eniallis, getting up after checking the goblin's vitals. "This one will live."

Alexander hears Eniallis say that the blood pact was god for something and all he can think is that it's brought nothing but pain to him. The looks of fear and mistrust given to him in every town he goes to hurts every time. It's only when they realize that he is also a paladin do they trust him. 

With a paind look on his face he says, "I did not choose to be a monster, a shell of a man, half-human, half-find. I was born this way and no good can come of it. Remember Eniallis, I did what I did to help the group but I didn't enjoy it."

Eniallis shrugs "I don't have first-hand experience, but from what I've read the pact is generally a bad thing for everyone. You tieflings get weird looks and mistrust while some weird-looking scroll even said that the demon who made the pact thought that he made a mistake later. Sadly random scrolls on such a delicate matter are quite hard to trust." he gets lost in thought for a moment. "I wonder if..." his voice fades into silence as he enters the cave.

Alexander enters behind Eniallis.He attempts to become stealthy, not wanting to give it away that they were here. Stealth roll: 3
