Chapter Select (CS)

You cannot run into another player in this level, though an early trailer shows two players on top of the first hill.

The First Hill
The player's Wayfarer starts in a field of sand, behind a large dune with three gravestones, including two large ones with with ruined scarves or ribbons tied into them. Trying to go any direction besides the hill will result in being blown back by a windwall. Walking to the top of the dune gives a thematic view of the mountain, which seems to call the Wayfarer to it.

(You will need to walk forward to continue.)
