It isn't hard to find a magical shop. Erevan's Enchanted Emporium in the trade district 

(basic map)

Kra-osh heads inside Erevan’s Enchanted Emporium, then looks around. Does anything catch his eye?

Perception check: 4

There is a lot of items here, nothing in particular stands out. You do see an elf behind a counter however

Ondrea will follow Petro to the bar, and is surprised when he doesn't perform.  She walks in to hear his order for Angorn and decides to sit nearby and make sure they don't get into *too* much trouble.

Angorn pockets his 2sp again, Thanks friend, He takes the ale sniffs it and wrinkles his nose a little sets it down picks up the mead and sips it a little Not bad!

Kra-osh turns to the elf, saying in a slightly tired voice: ”Hello, what are some of your more mundane, yet still interesting, magical or enchanted items?”

Petro pushes the shot of whisky forward to Angorn. Drink this in one gulp, then take a pull on the mead. You'll think me later. He sees Ondrea come in and sit nearby, and motions her over. He puts down another gold piece. She'll need a shot too. And whatever else she wants. Put it on my tab.

Ondrea eyes the the whisky suspiciously before taking a small sip and coughing.  After she recovers, she orders a mid-range wine and continues to watch the others get drunk.

Petro grins, and downs the rest of her shot.

Angorn, seeing Petro drink so much, he hesitates and slides the ale to the bard. I think I will just sip on this and the mead. Don't want to over do it my first time out. 

Petro shrugs and accepts the ale as well. Starting to feel considerably better about his circumstances, he waits for a good opportunity to start some music up: performance 19

Ramos walk into the bar a little later than the others, having lagged behind a bit. "BARKEEP! Something hard, if you wouldn't mind! I've had enough troubles for the day, may as well forget them all."

Kra-osh: the elf looks at you a bit, "Well I believe that my most interesting are out of your price range. But I have some I imagine you would like. What sort of items do you find interesting?" 

(Petro, based on how much alcohol you have had, make a con save) Ramos, you are given a brandy. "5sp please"

Obviously too much: 19

(But boy can he hold his liquor)

(You hold it enough that the performance isn't at disadvantage)

As Petro gets up to perform Angorn will go sit with Ondrea How are you doing after all the demon attacks? Do you think they will stop now?

Ondrea nods pleasantly at Angorn.  I'm fine, if puzzled.  It seems strange that demons would so persistently chase a caravan carrying nothing particularly interesting.  That makes me wonder if they were after someONE, rather than.  If that's true, we could see them again, if they're after one of us.  Aiden seems the most likely target, he clearly knows more than he's saying.

Angorn sips on the mead a little and nods That does seem a fair assessment. I normally prefer to only sleep out in the wilderness, but I think until this mystery is solved I shall have to stay in the city where there is others. I would be easy picked target out there by myself. 

Petro spontaneously composes a song about devils...and having sympathy for them maybe...and trying to guess their name. He tries to get Ondrea to sing back up on the "ooh oohs".

You all get a long rest and in the morning you find under your doors (rooms cost 7sp each and have 2 single beds in, or 4sp for a single room. Petro gets his own room free) a letter asking you to come to the castle to meet Artemis
