The World of Shadow and Bone

Ravka, the country where the story takes place and Smack dab in the middle of Ravka is the Unsea (aka the Shadow Fold) is a region of nearly impenetrable darkness that contains pterodactyl-like monsters that eat human flesh called colcra. It runs north to south in the middle of Ravka, and it cuts directly across the Vy, the main road that connected Ravka's capital, Os Alta, to Ravka's western port Cities.

The Fold extends to Ravka's northern and southern borders, and the country has been fighting the Border Wars with its neighbors for centuries. Fjerda, the country to the north, has Grisha hunters that kill or imprison people with powers who fight in Ravka's Second Army. Shu Han, to the south, guards its borders and is known for experimenting on Grisha. Ravkan people typically aren't welcome in either country.

This Fold splits the nation in two, effectively separating the capital city of Os Alta from the rest of the world. The Shadow Fold is super dangerous because it's full of creatures called Volcra that like to feast on human flesh, which you can't see coming because it's super dark all the time. The only ways to get from East Ravka to West Ravka without crossing it are to go through Fjerda (hostile northern country) or Shu Han (hostile southern country), so your options are pretty limited.

Toward the bottom of the True Sea (the actual ocean), you can see Kerch is the trade epicenter of the world and everyone who lives there is a cutthroat business person.

There are magic users in this world they are called Grisha ,Grisha are humans who practice the Small Science. They are traditionally divided into three orders, Corporalki, Etherealki and Materialki, with each order being further divided into specialized types.

Grisha were historically considered witches.The name "Grisha" is a diminutive of the name Grigori and is derived from the original Sankt Grigori, who trained the first Corporalki in Ravka.

In stories, Yaromir Lantsov, the first Lantsov king, prayed to the Saints to help defend his country against Fjerda and Shu Han. A group of monks who could transform into beasts arrived to fight, but had to endure the obisbaya ritual to return to their human forms after the battle. Those who survived and became the king's holy soldiers were the Priestguard. Some claim the first Priestguard were Grisha, and the animals they became were the first amplifiers.

The Grisha was classified into

Tailors are Grisha of the Corporalki order. They have the ability to change a person's appearance. Tailors were once considered rare and special; however, in Ravka, tailoring is now taught to all Corporalki students of the Second Army. Genya Safin was the first known Tailor and was considered a low-level Grisha who served the Queen of Ravka before the Ravkan civil war. In the Second Army they wear red kefta with blue embroidery.
