[First and foremost...]

Casz steps in behind Wagner, his interest largely waning. This place did have little knickknacks, things that could so easily fit in his pockets. But does he want anything? 

His eyes pan the room, searching, drifting...

[Passive Perception should work]

"Me! I am Xoblob. No relation to the eye tyrant hanging in the window!"

Casz, the shops sells trinkets. Purple trinkets of all sorts of variety. Pretty much anything on the trinket table is available here, but purple versions of them. There are signs around that say Enquire for prices

"What? Hey...."

It was of no use--Sterling's companions had already entered the shop. For his part, the young man just crossed his arms outside and did his best to NOT tap his foot impatiently as he waited for the others to quickly satisfy their curiosity.

 Caszimir, ever the one to provoke angst, steps out, grabs the grump's (Sterling's) hand, and tries to pull him in, a genuine grin on his face.

"At least come inside once. You might like what you find without realizing it."

Sterling was about to protest, but found himself inside before he could even utter a word. It was then that the unique color scheme of the shop caught his eye. Did this place sell amethyst? Fluorite? Charoite? Perhaps some unique and rare purple sapphires or diamonds? It would indeed be worth his time to acquaint himself with someone able to source such beautiful stones!

However, as he looked around, the bard's initial rush of surprise soured into disappointment, with a growing sense that the entire shop had to be a joke. He couldn't help but to actually verbalize his disbelief.

"What is this? Just... trinkets? All painted and hued to match your aesthetic?" He shook his head as he picked up a vial, constructed of a purple-tinted glass, and peered inside. Nail clippings?!  He set it back down, making sure to not touch the washed-out purple socks next to the vial.

"Who in their right mind would want such junk?"

Shaking his head once more, the young man said nothing further, and this time allowed his foot to softly tap.

Casz can only roll his eyes. 

"Thank you for your time, good sir." says Wagner, turning and leaving the shop.  Suddenly his eye settles on a glass eye, it's purple iris intriguing him.
Picking it up he asks, "How much for the eye?"

"Yeahhh... I had an eye on this big egg myself."

He holds up a rather sizeable violet egg. 'Maybe some kind of mount you can raise?' he ponders to himself.

Oriace steps into the monochrome curiosity of a shop, initially attributing the purple tint to the smoke and a dim light. Upon closer inspection, he realises that everything has been dyed by the shopkeeper. While not really interested in the trinkets, which he believes lose their value due to the gnome's poor taste in colour, Oriace still looks through the lower shelves, hoping to find something overlooked by taller customers. As he approaches the gnome shopkeeper, he engages in conversation, remarking, "Would you believe it? Zhentarim and Xanathar's thugs are at each other's throats again, even picking fights on the streets now! What could possibly be driving them to such aggression? There's something suspicious going on, I'd say."

"The eye is 5gp. And the egg is 3gp."

He nods at Oriace. "Very sad for business, especially when it happens right outside the shop. Talking of, are you buying anything?"

"Not sure," replies Oriace in his low rumbling voice, "I'm more inclined towards earthy browns and lush greens when it comes to colors, especially those found in nature." Then his eyes lock onto something when he took it out of the shelf almost unconsciously: [47] a metal can that has no opening but sounds as if it is filled with liquid, sand, spiders, or/and[?] broken glass [your choice]. "How much is this?" He asks casually, punctuating his question with a nonchalant shrug (Charisma: 11). "It doesn't seem to be very valuable, perhaps the metal it's made from. I'd part with a few silver coins for this trinket. The sound reminds of the sea."

"Very good craftmanship, and high quality materials inside. Yours for just 2gp yes."

„It’s a can! Outrageous!“ Oriace exclaims, „10 Silver coins. For more, I can just go a few times to sea and listen to it naturally!“

"Purple metal is very rare and I have been assured that the contents of the can are equally purple. 1 dragon and that is my final offer."

(I am going to start trying to make an effort to refer to coinage using the Waterdavian mintage terminology. See ooc chat for more details)

"Now have you?" Oriace cries out, "I pay you a dragon and five shards but if you accept that we open the can and if the content isn't purple you return me my money threefold! If you aren't even that sure, I think you're trying to take me for a fool and I won't pay more than 5 shards for the thing." 

"If you are going to accuse me of being a liar, then I want no business with you!" and he takes the can from you and puts it behind the counter. 

Caszimir narrows his eyes, but gives his best warm smile. "How about one Dragon, and I tell everyone I can at my next show about your business?" He leans against the wall and gives a flourish with his hand. "Can't imagine you'd get much advertisement, being in this part of town. I'm offering it cheap, I'd say."

[Persuasion: 19]

"Ha!" Oriace lifts up his empty hands in resignation, "You don't even feel that your own word is worth five silver shards, you snake! How can anyone pay you more than that? I wonder if you already took advantage of others. I will certainly enquire!" He turns and marches towards the door while calling to his companions, "I'm outside until you're ready to go to the Skewered Dragon." He adds with an angry look on his face directed at the gnome, "And that's where I will start to ask about your shop." Then, he leaves the store to wait outside.

(Intimidation: 18)

"You say I don't get much advertisement, but it sounds like I am about to get some advertisement at the Skewered Dragon for free. But a bit more never hurt." and he flips Casz a single dragon. (not purple)

Slightly embarrased, Wagner simply plunks 5 dragons on the counter and walks out with his eye.
