Shattered Darkness is a novelization of the sequel to the Nintendo GameCube title Luigi's Mansion. It aims to add upon the story aspect of the game via the introduction of new characters, specifically Vivian from Paper Mario: The Thousand-Year Door.
Aside from the new characters, it seems to follow the original story closely... so far. With only two chapters including the prologue, it's a very new fanfiction. Only time will tell if it ends up being as well-received as the game it is based on.
The fic itself can be found here.
This fanfiction contains examples of the following;
- Deadpan Snarker: Vivian at times. Lampshaded by Luigi.
- Noodle Incident: Apparently Vivian tried to use the Poltergust once and... failed miserably.
- Oh, Crap!: Luigi gets a few during the first main chapter.
