There are many different types of Grisha, and they are typically determined through a test as children. If a child is determined Grisha, they are mostly separated from humans and taken off with other Grisha to learn how to hone their “Small Science” skills. There are three main types or “orders” of Grisha: Corporalki, whose power lies in the human body (such as a healer), Materialki, whose power lies in materials (such as an alchemist) and Etherealki, whose power lies in the natural elements. Shadow and Bone’s protagonist Alina falls into the Etherealki category, since she can summon light. The Grishaverse explores these people and their stories through different lenses.
