((Side note: I am running this with the assumption that everyone is keeping their room at the inn reserved even when out on an adventure. If you want to unburden the weight of carrying monster parts until you can sell them, you can leave them in your room. There's only a small chance someone would break in and take them...))

Sael nods, somewhat expecting this.  "I wouldn't mind selling my longsword.  Little damage to it;  I use my boomerang more often.  This land however calls for something else.  I'd like to purchase 2 Handaxes, a shortsword, and a whip."

Linene nods. "We could do that. Can I take a look at your sword?"

Sael unsheathes it, tips it sideways and hands it handle first to Linene.

Linene takes it from Sael and looks it over. She says, "I'll give you 7 gold for it. If you buy everything you said you wanted..." she takes a few seconds to add everything up. "All of those things together would be 22 gold. With the 7 gold for your sword, I can sell all of that to you for 15 gold."

• 7gp for the longsword
• 10gp for 2x handaxes
• 10gp for a shortsword
• 2gp for a whip

10+10+2-7 = 15gp

Kwisatz would have asked if there was a stables to buy a pony (https://www.dndbeyond.com/sources/phb/equipment#MountsandVehicles), otherwise lunch and a rest to finish copying a spell.

Yeah, there are no stables in Phandalin, unfortunately. But, go ahead and subtract the materials and/or gold that you have left to subtract and add the new spell to your known spells list.

"Sounds about right," Sael says in a mildly upbeat tone.  She hands over 15gp. "Will you be needing the sheath?" 

"Yeah, I'm gonna need polish it up a bit if I'm going to resell it."

Sael un-threads it from her belt and hands it over as well.  "Thank you," she says, taking her purchase.

As Sael finishes up her business, Andrømeda steps toward Linene from where she'd been idly looking at the different items for sale. "Hels dir, Am just vant to ask, du only buy and sell, or are du able to smith a våpen stronger?"

"Sorry, dear, we don't have a smithy in town. The nearest smithy would probably be the dwarves that used to live in Axeholm."

Andrømeda nods, not surprised but still a bit disappointed. She glances around the shop one more time, and then snaps her fingers, cursing, "Dritt!" Remembering that she didn't retrieve the Javelin she'd struck one of the Manticores with. "Am vil net a kastespyd," she says, pointing at the javelins. "Just de one, please."

"Coming up. That'll be 5 silver."

Andrømeda passes her the coins, thanking her and taking the Javelin, tucking it on the side of her pack with the other three before turning to Sael. "Vell, if vi are done, shall vi go and fill our bellies?"

"Absolutely," Sael replies, finishing tying the weapons to her sides.

Sael and Andrømeda finish up at the Coster and head back to the Inn to get some lunch. The innkeeper greets them with a smile. Kwisatz is upstairs in his room, learning his new spell, and ((I'm assuming)) Rush has been with them. 

It took you ~30 minutes at the Coster, and then it'll take another 30 or so minutes to get and eat your lunch. So, by this time, we'll estimate that it's about 11:00am when you're finishing up lunch. Kwiz will have finished studying his spell and learning it by this time, as well.

So, you're free to take whatever next step you'd like to. Based on the map that Kwisatz got, you know that Butterskull Ranch is about 60 miles away, and it'll take you 2 days worth of travel to get there. You have about 6 or 7 more hours of daylight before the sun will be set and your first day of travel will be over. (Unless you want to risk traveling at night and either exhausting yourselves or running into some sort of dangerous night creature.)

Sael heads to the others rooms and knocks on their doors.  "Ready?  We can probably get a good 5 hours or so of travel in if we head out now."

Kwisatz stands up, stretches his legs out a bit, and says "Let us be off then. These old legs get a bit sore doing any one thing for too long. Duncan will keep a lookout as we go as well."

As they walk he'll send Duncan up ahead to scout from time to time: 11

You collect yourselves and your gear and you make your way towards Butterskull Ranch. You take Triboar Trail. Traveling is relatively uneventful and as the sun starts to get low on the horizon, you arrive at what was the town of Conyberry. The abandoned town is eerily silent except for the whistling of the wind as it blows through the settlement’s burned and crumbled-down structures. The party notices that there are stretches of ruins that are frozen with melting ice. You notice it because it's not winter time. (It's late summer/early fall.)

As the party make their way through or around the ruins, they spot three unsaddled riding horses grazing near an old well.

Perception Checks:

• Andrømeda: 5
• Kwisatz: 3
• Rush: 24
• Sael: 15

Andrømeda and Sael notice that the horses are branded with the initials "BAK".
