Alina Starkov is a teenage girl who grew up with Malyen (Mal) Oretsev at an orphanage in Keramzin in the Kingdom of Ravka. The story begins as they march through the Unsea (also called the Shadow Fold), a perpetually dark, barren strip of land cutting most of Ravka off from the sea. Periodic expeditions sent across the Fold to transport goods and bring back imports are often plagued by monsters called volcra that inhabit the Unsea. During their crossing, the volcra attack, and, while saving Mal, Alina displays an extraordinary Grisha talent. The Grisha are people with the ability to manipulate the elements to use as weapons, e.g. to call fire, to summon wind, to regulate hearts. Alina is able to summon light and is thus considered a Sun Summoner. There are some people who think she is a saint whose purpose is to destroy the shadow fold.
