As a total paratrooper in the role-playing genre, Clair Obscur: Expedition 33 had a whole bunch of expectations to deliver on. Whereas a lesser franchise might choose to keep things neat, simple, and straightforward from a backstory point of view, Expedition 33 instead goes all-out with a setup that even the weirdest of Weird media wouldn't be ashamed of. Oh, sure enough, the story is strange, and that's precisely what makes it so interesting.
We're not about to go knee-deep into spoiler territory here, then, but you're absolutely going to need to be aware of some key terminology in Clair Obscur: Expedition 33, as the game doesn't go out of its way to explain itself. For example, though you may hear about the infamous Fracture, no one's going to outright explain it to you. So, here's the jig.
The Fracture is Clair Obscur: Expedition 33's defining catastrophe. This world-changing event took place exactly 67 years before Expedition 33 sets off to hunt down and kill the Paintress, and it effectively isolated the city of Lumiere from the rest of the mainland Continent. The exact what, why, and how of the Fracture gets explained later on in Expedition 33, but the gist of it is quite simple, then: it's a civilization-ending disaster that sets up the end of humanity.
Following the events of the Fracture, both Lumiere and the Continent were effectively ruined, and the Paintress kept counting down from 100 (or 0, as it were), wiping out all humans of the numbered age as she went.
There are more complications to keep in mind along the way, naturally. Like who the mysterious old killer was, what's up with all those Nevron creatures, and what was it that triggered the Fracture in the first place. We promise: you do not expect the answers you'll be given, and this is easily one of Expedition 33's strongest suits. Just be prepared for a whole bunch of Weird along the way!
Oh, you thought you knew Weird?
