* Champions of the Just - The Herald can use this perk to suggest getting in touch with their contacts in the lyrium smuggling market, as a way to supply the soon-to-be arriving templars. This will unlock the war table operation Secure More Lyrium for the Templars.
* In Hushed Whispers - The Herald can use this perk to suggest getting in touch with their contacts in the lyrium smuggling market, as a way to supply the soon-to-be arriving mages. Unlike Champions of the Just, this will not result in any war table operations.
