I used an Internet Archive backup to play this game.
In it, you start with a one-sentence story, and then expand on it. After three or four rounds of expansion, you get a full-fledged story.
There is quite a variety; I found a cheating king who broke his wife's heart, an evil witch who sucked the life force from her husband, and a mysterious assassin who married the king and left her old life behind only to be forced to return to her old habits.
The structure seems to be completely branching, which makes sense as Inklewriter isn't an exceptionally powerful engine. There may be some state tracking, though I'm not sure.
Overall, the stories were each high quality, but this overall feels slight in terms of its interactive structure.
