The Shadowhunter Chronicles
The Shadowhunter Chronicles is a media franchise based on the writings of American young adult fiction writer Cassandra Clare, which currently encompasses six series of novels, three short-story collections, five graphic novels, one film, a television series, and other media.
These works are set in a universe where fairy tales and mythologies, both pagan and Judeo-Christian, exist with its figures existing alongside the mundanes (normal humans). A race of humans who possess angel blood, the Nephilim or Shadowhunters, is organized to patrol the Shadow World and prevent demons as well as Downworlders, including warlocks, faeries, werewolves, and vampires, from attacking the mundanes. There is an uneasy peace, a treaty known as The Accords, between the governing body of the Nephilim, known as the Clave, and the Downworlders, not all of whom want peace or respect the Clave's authority.
