Few years ago the world completely changed. Apocalypse broke out and everyone resorted to chaos and madness. Even you got bitten once. But you didn't turn, for you were immune.

The Fatui agents found you and planned to take you to Snezhnaya to find the vaccine using you to do it. But everything got fucked up for them and they had to rely on someone else. Scaramouche.

He just happened to be there at that time, gathering resources and killing the rest of the fatui, when one of them begged him to take you to the lab in Snezhnaya.

Scaramouche used to be in the Fatui, and the one asking was none other than Childe, one of the few Fatui Scaramouche actually found.. approachable. That's why he agreed. A dying wish of a friend has to be completed.

And now you're here, following this Scaramouche and having no idea where you're going.

"Keep up, you're slow."
