350 sir, double your cost and a little extra

Persuasion 14

Pyllrak agrees to the 350 gold pieces. 

(Before you hand over the gold I have a question for @Pertuie: Do you want to negotiate with Kazmojen for the release of Krylscar. Since the party has chosen to negotiate instead of fighting, he won't let you keep exploring the fortress freely. Maple does know a back way to the cells, but if you choose to go that route after business here is complete I will add a chance that you run into Kazmojen in any given room.)

Ooc: sincerely, even if he understands the course of action in place, being a vengeance paladin Oreus wouldn't dislike a fight

Rellahne decides to move to the front and attempt to diplomatically attempt to make them release Krylscar. "Wait, we're not done yet. There's one more person, the man I've come here looking to find. His name is Krylscar. Where is he, and how much for his release?" Her look is serious as she turns to Kazmojen while saying that and waits to see what would be the dwarf's response.

Kazmojen says to Rellahne "I don't keep track the the chattel names, let me check." He then moves to the western door and opening it he bellows "Zarkad, get in here" 

A few minutes later an ebon-skinned hobgoblin with one arm appears. His armor has a patchwork of blood stains both old and new. He asks in Goblin (which Tyris can understand) "What can I do for you Lord Kazmojen?" Kazmojen asks in Goblin "Do we have a slave called Krylscar? If so go fetch him. The hobgoblin replies "Yes" and leaves. About ten minutes later Zarkad hauls in a young man who looks he has been badly beaten several times, and Kazmojen says "Oh, that one. He's keeps insulting my clients in the worst ways. Nobody will buy him give me 20 gold pieces and he's yours"

(So here is the breakdown 

• Terrem costs 160gp payable to Kazmojen 
• The other three children costs 350gp payable to Pyllrak 
• Krylscar costs 20gp payable to Kazmojen 
• Total cost of all five individuals is 530gp.

Assuming you have that much gold in which order do you want to make the transactions?)

Shadow will pay for Terrem first, and we will need Tyris to go pay Pyllrak.  If Rellahne doesn't have the 20, Shadow will pay that as well then

Shadow tells Kazmojen that he is now ready to pay for Terrem, and starts approaching the black armored slaver. Suddenly as Shadow is about halfway to Kazmojen's position, a Beholder materializes next to Kazmojen and says to him  "I have come for Terrem Kharatys. That boy should not have been taken from Cauldron. I intend to see that he is safely returned to his orphanage. You can keep the others. They are of no consequence. Come, Terrem – you will be safe with me." 

How do you all (everyone) respond?

My companions and I have just concluded our business here and will be taking them back to cauldron ourselves.  We were charged with finding them and have agreed to pay for them.  If your intentions are as you say, then follow us back to cauldron yourself to verify our words

At the cost, Rellahne looks a bit nervous at first, but seeing Shadow spring up to help her pay, she responds. "Actually, you don't need to cover for all the price. Just 5 gold coins should work, and I can pay the rest. I'll hold on to that as a debt I have yet to pay back, but thank you very much either way."

How does Rellahne, Oreus, and Tyris react to the Beholder?

Oreus is not surprised anymore by shadow's cold blood. 

Ooc: what do our characters know about beholders and their presence in Caldera?! 

(Beholders are the stuff of nightmares. These creatures, also called the "spheres of many eyes" or "eye tyrants", are deadly adversaries. Most people have heard stories about Beholders growing up. Usually to the tune "You better shape up my lad, or a Beholder might get you". As far as you know there isn't a beholders in Cauldron.)

Rellahne was immediately put on guard after seeing the Beholder appear. She heard enough about them and was scared this one would be hostile, or at least very untrustworthy.

Insight 14

Tyris' eyes narrow and he tenses as the Beholder appears.  He nocks an arrow to his bow, but doesn't yet raise it, waiting to see how the creature responds to Shadow.

Deception 21. Rellahne knows that the Beholder is ultimately serving a long thought out strategy and is up to no good, however ot the moment (you believe) he doesn't havd any hostile attentions towards the party and you both have the same short term goal.

Oreus?

Oreus speaks to the beholder, caring not be too close to the monster and hoping to show as much cold blood as Shadow 

Addressing Shadow

"my friend's words are true, we stroke a deal and the boy is now ours. Anyway, it is the first time I see one of your kind in Cauldron and, well, sorry to say but at least in legends your race is not considered very keen with children... Quite the opposite... How comes you know him by name and what is your interest in him? "

The Beholder replies to Oreus and Shadow "Aw, but you haven't paid for him yet, and I can outbid you." 

Turning back to Kazmojen, he says "Master Kazmojen, here is 50 platinum pieces for the children Terrem. I will be taking him now!" 

At this point a black clad veiled woman who appears to be flying becomes visible and flies over to Kazmojen and hands him a full pouch. Kazmojen knows that he is outclassed and stammers an agreement as he takes the pouch. 

The woman takes Terrem's hand and starts a spell.

(If you want to attack them, or otherwise prevent them from leaving you have a round to do so. Everyone let me know if/what you are going to do. If no one does anything the beholder, woman and child disappear as they are teleported away. )

Ooc: a little of metà gaming... What do we want to do? IMHO there is no much choice, there is a precise reason why they want the kid and if we survive we can understand why and it might be a turnpoint of the whole story

If everybody or majority agrees, this turn Oreus would move next to the kid and pronounce ABJURE ENEMY to scare the woman

In case, initiative 18

Do we recognize the woman? I have one thing I can try to stop them if we are going to interfere
