 You're **Sheltered** with a roof overhead and walls in at least six of eight directions. A roof alone keeps the rain off you and your fire. A campfire works fine indoors. The **stone hearth** warms a room half as wide again as a campfire, its chimney keeps the rain out, and it cooks. A **fur rug** in a sheltered room makes you Cozy.

+Indoors at night it's dark unless something is burning. A **tallow candle** (a lump of bear fat and a fibre, by hand, makes 4) lights a small room with a steady glow for about 7 m. A **torch stand** (2 wood, 2 sticks, 2 fibre, by hand) flickers like a torch and lights about 11 m: a whole hut or a doorway. Both stay lit for good, need no fuel and give no warmth. `X` takes them back up.

 ### Beds
 
 `E` on a bed makes it your spawn point. Once it's yours, `E` sleeps until 06:00, if it's between 19:30 and 05:30, the bed is sheltered, and no wolves are prowling within 40 m. A **bedroll** (3 hide, 6 feathers, 4 fibre) works the same but needs no shelter: you can sleep under the open sky, as long as it isn't raining or snowing. While you sleep, fires burn, kilns and smelters work, things regrow and food spoils. You wake dry, warm, full of stamina, Rested and a little hungrier, and the game saves.
