While the TV shows adapt two book series, they re still from the same universe called the Grishaverse so most of the elements remain the same.
Shadow and Bone takes place in a war-torn world, separated by the mysterious Shadow Fold (or simply called the Fold in the show) which is crawling with winged monsters, Volcra, that feast on human flesh.
Upon the Fold s accidental creation by the Shadow Summoner or the Black Heretic, it splits the country of Ravka into two East Ravka and West Ravka which leads the whole country into years of war and conflict.
It follows Alina Starkhov who initially believes she s just a simple cartographer but has suddenly unleashed an extraordinary power that was just thought to be a legend. Her powers could be the key to destroying the Fold and setting her country free.
