A Court of Frost and Starlight (ACOFAS) is the fourth installment and the first novella in the ACOTAR series by Sarah J. Maas.

Taking place several months after the events of A Court of Wings and Ruin and the second Human and Fae War with the King of Hybern, Feyre and her companions recuperate from the trauma and exhaustion of the war and prepare for Winter Solstice festivities in Velaris. This guide offers an in-depth look at the world in ACOFAS. For a deeper exploration of the characters, please visit the Ultimate ACOFAS Character Guide.

Prythian is divided into 7 Fae courts each with its own High Lord, unique landscape, and local culture. At the center of Prythian lies the Middle, an empty territory under no one’s jurisdiction and which acts as a neutral meeting place for all the different courts. The Middle also divides the northern Solar Courts from the southern Seasonal Courts. At the bottom of Prythian lies a giant wall that separates the Fae lands from the Mortal Lands, a designated territory for mortals that keeps them safe from the Fae. Beyond Prythian’s western shores lies the continent of Hybern, a militaristic Fae kingdom steeped in old magic and under the rule of King Hybern, who seeks to once again enslave all mortals. To the east lies the Continent, a large mass of land ruled by the Mortal Queens and similarly divided with a wall to separate the Fae from the humans.
