((I'm going to assume you guys are following Snowy up above the snow-line.))
You begin your trek towards the area covered by Widdle's map. The first leg of the trip is due north, cutting across the open grassland between Silverhaven and the snow-line intentionally left farm- and road-free for defensive purposes. The wagon bumps over the divots and molehills at a pace only slightly faster than a walk, but the weather is unseasonably mild and everyone is in good spirits. You camp on the plain under a blood-red moon, sharing a bottle of spirits that Boon smuggled out of the Tiny Lancer.
As you talk, it occurs to you that tomorrow night is the Hallow Feast, and it's the first year you won't be joining with the others back home, eating, singing, and dancing. It's a sobering thought, but even a reminder of where you've come from can't dampen the excitement over where you're going.
The next day dawns cold and clear, and you can hear the high, keening screech of eagles soaring high above you.
The air grows chill when you cross over onto the snow. Everyone had put on their heavy leather and wool coats a couple of miles back, and is glad of it now, though there's little wind. You have to stop every so often to check the map, looking for landmarks and trying to find the area Snowy remembers. A little after mid-day, she suddenly orients herself and marks your place on the map.
The going is fast, now, and the anticipation (and, you must admit, slight nervousness) grows as Widdle's map proves as accurate as you'd hoped. The wagon crunches over a frosted hill, and ahead of you rises a jagged fist of slate, peeking out above a copse of withered spruces. That's the one, you can feel it. Your breath quickens.
Rolling into the trees, you come upon a clearing around the face of the mound. You know you've found the right place -- an ancient weathered archway with the remnants of a runic symbol carved in the keystone, opening onto a cave that descends into the mound. Arrayed around the entrance are a number of animal corpses in various states of decay.
