Ley lines are the province of the fey. Ley lines converge at sacred sites, forming a matrix within which magic is amplified.[1] The Adamant Citadel is also said to be built on ley lines—this granted the faeries and their Dark War ally access to the typically remote location.[2]

Ley lines are used by Downworlders to create entrances into the Faerie, among others. Faeries in particular use them often. Though invisible, one can be trained to sense ley lines.[3]


  • The term ley lines and its use in The Shadowhunter Chronicles most likely refers to the concept usually associated with Celtic folklore: the spiritual and mystical alignments of land forms, similar to a spirit or fairy path—a route taken by fairies usually in a straight line and between sites of traditional significance.[4]
