A secretive criminal organization that operates primarily in the Fey Realms. Danaus is known primarily for illegal magic item trafficking, especially in forbidden artifacts and things of that nature.
The insignia of the Danaus group is a monarch butterfly.
According to Tertia Quattrocchi, Danaus was involved in the events on Epsilon Marut, including the kidnapping of Gimmelon Mikaelson. She also concluded that Raziela was in collusion with this organization.
In FanOut Gaiden, the insignia of Danaus appeared in footage relating to the origins of Killroy’s sunblade, along with a woman who resembled Raziela.
