The Downworlder-Shadowhunter Alliance is an organization comprising of Downworlders and Shadowhunters cooperating and working together to further establish peace between their kinds.


The earliest incarnation of the group was simply a small gathering of minds between Magnus Bane, Lily Chen, Maia Roberts, and Alec Lightwood, who later became known as the founders of group. The first discussions were solely to resolve issues and Cold Peace conflicts in New York City.[1] They were soon joined by Jace Herondale and Clary Fairchild after their appointment as heads of the New York Institute, and later by Isabelle Lightwood, Simon Lewis,[2] and the members of Lily and Maia's respective clan and pack.

They gradually became famous and were sought out by others needing help across the world,[1] sometimes also coordinating with Institutes.[3] By 2012, the Alliance was receiving a steady stream of Downworlder visitors looking for help because they felt they couldn't go to their own Institutes.[4]

After the Clave was exiled from Idris, the Alliance led up the effort to build the new Shadowhunter Academy in New York.

With Alec expecting himself to be busy with his new duties as Consul, he approached Mark Blackthorn and asked him to help head up the Alliance as an ambassador to Faerie along with Cristina Rosales.[3]


  • Rumors circulated in 2012, spread by anti-Downworlders, that the Alliance was being shut down.[5]
