(You've got a lot of confidence in your players' ability to recall information for extended periods of time)

"Thank you for opening up your home to us and I do hope that we can take advantage of your offer some time in the future." Percival will say before ushering everyone out of the house. "We should get on the road. At best, it'll take four days to get to Ten-Towns and that's assuming that the weather holds up and we aren't accosted by anything." 

At this point, the latter is beginning to become an unreasonable assumption.

PERHAPS, BUT DO NOT CONSIDER IT A CURSE. HOW ELSE WOULD YOU INCREASE YOUR PROWESS WITH THE POWERS THAT I HAVE GIFTED YOU IF NOT THROUGH COMBAT? IT IS HERE, IN THE COLD, THAT YOU WILL BECOME STRONGER. I HOPE THAT YOU ARE BEGINNING TO SEE WHY IT WAS IN MY DESIGNS FOR YOU TO BE HERE.

It's making much more sense now, yes.

GOOD. THIS WOULD BE MUCH MORE TEDIOUS IF YOU WERE A SLOW LEARNER.

Hence the reminder, ah?

(I assume Lucas is navigating for us, so we won’t treat it as difficult terrain? 😉)

Sobek takes a deep breath as he steps out of the door and into the wild, and you sense that he’s entered his element, even if this tundra is not his natural habitat.

He takes the rearguard position, watching over the group and making sure no-one gets into trouble as they travel.

Vetis seems, as usual, unconcerned with the cold as she walks at the back of the group.

Mini encounter one:

Just past midday, you come across a smashed cart at the side of the road. Two sets of tracks lead away from the cart into a grove of snow-covered fir trees.

"I'm going to pretend that I don't already know the answer to this and ask if we want to follow the tracks and find out who or what smashed this cart."

Sobek crouches down to investigate the tracks.

Survival: 5

Ava shivers a little in her armor looking around the cart. "Sobek, what have you found?"

Lucas is indeed leading the party through the trek, allowing them to keep a steady pace despite the difficult and chilly terrain, noting to the group that unless they take a detour or get sidetracked, he should be able to bring them to the location much quicker than the original 4 days it would have.

As they're travelling, he would be keeping his eyes open and when the party encounters the cart, he would also join Sobek in identifying the tracks.
Survival: 25

You find a tattered letter in the cart which reads: “To be delivered: 100 gold pieces for moneychangers in Bryn Shander.” Nothing of value can be found in the cart, other than a week’s worth of trail rations.

Two sets of tracks lead away from the cart, moving parallel to each other. One is a set of humanoid bootprints, the other are the hoofprints of a horse.

DC 12 Wisdom (Survival) check: ?????

Kai let's the survival masters handle the tracks, just being sure to stay near Ava and whoever looked to be struggling with the winter chill.

Sobek looks at the rest of the group. ‘Looks like someone might need some help with the rest of their journey. We should check on them.’ he growls.

Survival: 22

Sobek, you note that at some point, the humanoid tracks disappear, perhaps having swung themselves onto the horse, and the tracks lead into a fir grove. You follow the tracks for about a half-mile into the grove, and find a grisly scene at their terminus. The carcasses of a half-elf man and a horse are both frozen and half-eaten by scavengers. Wolf prints can be found in the snow. The man is clutching an iron lockbox.

"That is not pleasant. Poor fellow." 

"Sobek, Lucas, can one of you follow these wolf tracks."

Vetis blinks, then after a long delay, likely after everyone else says their piece, says absently, "How unfortunate."

Sobek checks the wolf tracks to get a sense of numbers, make sure they’re natural, and looking for signs they might be carrying injuries.

’Wolves wouldn’t normally attack a human or elf, not unless something is seriously wrong. The horse would have been enough. It wouldn't just be half-eaten either.’

Survival: 20

Unfortunately, you're not able to discern any additional information on the grizzly scene.

Kaz looks at the scene and shrugs, “mmm, gross. I would hate to end up like this icicle of a being, let us continue on, yes?”
