What's the smallest thing in your story that, if removed or altered, could change your novel's entire plot? Will the entire world in your story be doomed, or will it remain the same as in the original plot? Will the protagonist be happier if that small thing is changed? For example, in the anime AoT, the entire world almost got destroyed because of the events that led from a girl releasing a pig from a farm.

You can go wild advertising your story by linking it here just make sure that you talk about atleast most of the questions or in general.
The entire multiverse could collapse from a disruption in the balance between worlds, and the Elements, Life, and Death.
If
Morrigan (Her game-character's name) didn't face the intense trauma of her past, all life in Elaria will end (it still might anyway, only time shall reveal the true fate of the worlds).
In truth, there are a number of causal events that all need to occur in order for the balance of the Great Cycle to continue as it must to sustain the multiverse of my "shared universe", and some of them are as small and mundane as a young woman walking down the street on a particular day, at a particular time.
Chance encounters.
Synchronicity.
Fated Coincidences.
Relics and Remnants of the past.
Lost Echoes giving birth to New Legends.
All things shall come together in the end.
Even the darkest of times can give birth to the brightest of lights;
So long as the fires of Hope continue to burn in the hearts of men.
