Story Line

The game is fragmental, without the introduction or the ending or any explanation of what is happening. However, there is likely to be the story line relating the characters and the world they inhabit. Obviously, the story line is still being developed as the game is being expanded. The main sources revealing details about the story line are the promotional videos, hidden puzzles and the game itself.

For instance, Don't Starve Cinematic Trailer Forbidden Knowledge reveals how Wilson ended up in this world. For the puzzles see William Carter Puzzles topic. In the game Maxwell refers to other players and objects, for example, says that he kept Wes locked out since Wes is weak.

There are many nice details in the game, like how characters refer to objects which one could analyze and the infer about the story line.

In one of the posts on Klei forums one of the developers outlined the structure of the story as they saw it at that time

1890s - 1906: William Carter origin story 1906: William and Charlie enter the DS world. 1906 - 1910ish: Some crazy stuff happens that we haven't told you about  yet .... 1910ish - 1921: The various playable characters get pulled into the DS world. 1921: Wilson gets pulled in (Forbidden Knowlege trailer). * THE ORIGINAL GAME + ROG STARTS HERE* ?: Wilson lives in DSworld for a while. Dies a lot, eventually finds Maxwell's door and confronts Maxwell ?: Wilson replaces Maxwell on the Nightmare Throne, Maxwell becomes Waxwell.

?: Some other crazy stuff happens that we haven't told you about  yet ....

?: The DST plotline begins.

It is not known if the developers are interested and will be developing the story line and if there will be more game updates or if the focus will shift.
