So, again, the goal of this one is not terribly intuitive.
There will be various places you will visit that will have a star in the upper left hand corner of the card. In addition, in the upper left corner of the screen, you will see a temperature gauge that usually rests on 5 or 6. When you are at a location that has a star, part of your goal is to get the temperature gauge up to 9 before you travel. This is really only done one way, and that is sacrificing your survivors to your top special ability to raise the temp by 1 point. The game is won when you have done this at 5 different star locations. I, myself, completed this around day 52 in the game time. (Yes, also killing the grizzly and other obscure ways raise temp, but realistically, your only reliable hope is setting your friends ablaze)
As such, you'll want to be sure to travel with a surplus of survivors. Have them scavenge as much as possible to find other survivors, the event where you can trade fruit for survivors is a godsend in this mission as fruit is your most bountiful item and often has the least utility use as you get into the late game.
Don't be shy about sacrificing wood to the priest's lower ability, which lets you draw 3 from the top of your deck. This is where you can have your scavenges pay off extra. If you don't get a survivor off the scavenge but get wood, sac the wood to draw more survivors and repeat. Just be sure to have a way to generate more wood as you'll burn through a lot. (Get it, burn? Haha it's late I'm sorry.)
Also, be aware, temperature will reset once you travel. So there's no great reason to try and build up temp 1 level at a time. Just go all or nothing when you get to a starred location.
And finally, make sure you have a few outlets to remove fatigue. Cooks, shelter, and even pets can be a routine clean-up. That will make your draws cleaner and guarantee more success to dig with wood or find more survivors. I would say the ultimate idea card to look out for is the shaman, who lets you use that low-value fruit to push the frost clock back a day, and let you scavenge ad-nauseum once you get the deck to a manageable level of fatigue.
This is a rough one, and you'll likely restart a lot until you get a game with the proper opening.
