    • +
  • Wolves move in, and every seventh night the moon turns red.
    • +
  • Weather that matters: storms, blizzards and hard winters.
    • +
  • A bear, a barrow, and the Old Stag at the standing stones.
    • +
  • Play alone, or host a server for friends on your own machine.
    • +
  • A guided tutorial with Old Tam the hermit.
