This is the last story of this arc.
This specific story does not fully cover the whole event. To see serveral missing pieces, you need to read [Juron arc]  [Bright Red] .
Don't know where to begin?
While ultimately it doesn't matter which arc you begin with, Cecil arc is recommended if you want my recommendation.
And then Masu arc + Shattered union arc.
Feel free to visit the lore section as well which holds stories of its own.
