Start off as a pre-existing band of adventurers, in medias res. Pick 2 each of 8:

Bitty Bee - Pegasus, rogue, mare

Big Tuck - Earth pony, fighter, stallion

Pepper Papers - Unicorn, scholar, mare

Green Bud - Earth pony zony, herbalist, mare

Soaring Stratus - Pegasus, weatherpony, stallion

Moon Magic - Unicorn, mage, mare

Arrow Weed - Earth pony, ranger, stallion

Brass Bobbins - Unicorn, tinkerer, mare

Party items: (Carried by Big Tuck, unless you decide otherwise.) A tent. A lantern and oil. A small cookstove. <$1500> in Equestrian money. <$200> in precious metal coin, mostly Yakyakistani. Slow-Magic Lantern in which to put the Embers (quest item; carried by Green Bud)

Everyone additionally has uninteresting supplies (food, sleeping bag, water) although consumables are running low at this stage in your long journey. You have consumables for 3 days remaining.

Your band of adventurers were caught by the ELDER DRAGON Nares of Corundum trying to rectify a situation of profound economic inefficiency, to wit, the existence of the same dragon's vast unused hoard of precious metals, and were thus rather unfairly presented with a choice of either being burned alive or accepting a MAGICAL GEAS to perform a quest for him. You can still hear the words of the greedy old lizard ringing in your ears - literally, in fact, as that's part of the geas and seems to happen randomly at the most inconvenient times:

This quest has taken you into the farthest reaches of the FROZEN NORTH, through perilous Yakyakistan and the hostile wilderness beyond. Finally, you have arrived in the outskirts of the REINDEER KINGDOMS. It has been a long and been a long and difficult journey, and your supplies are running low.

Trudging through the arctic darkness in newfallen snow on your way to a settlement in the distance, you are suddenly ambushed by great hairy white yetis!

(They should be pretty tough. EL may bail them out, but will want payment.) "Lore, of Equestria. I am a journeymare of the Arcane Helix."

EL is going to try to filch the Tome of Ursami when it is used in the Winter Solstice ceremony on 30 Crafting.

Ceremony - the high priest of the Reindeer, Sajiyule, will open the wards of the Great Boreal hearthfire to make an offering to it, consisting of everwood (preserved by freezing). He will read from the Tome of Ursami, casting the spell to renew the hearthfire, burning up his own antlers and losing his magic until they regrow. (This is obviously when EL will try to steal the book.)

The wards are closed at this time (by underpriests) until the next year.
