Nameless Ones were an ancient order of priests who worshipped the Azath Houses. Their origins date back to the time of the First Empire.
They consider themselves the servants of the
Azath, the shapers of their will.
Spite is one of the Nameless Ones.
It was revealed that
B'ridys was an ancient monastery of the order and also that the Tanno claimed that their faith was a direct descendant of the Nameless Ones.
The Nameless Ones were responsible for releasing
Dejim Nebrahl and also employed the Gral tribesman Taralack Veed to replace Mappo Runt as Icarium's companion.
It was revealed that, contrary to Mappo's belief that Icarium had murdered his clan, it was in fact the Nameless Ones who had done the deed in order to manipulate Mappo into becoming Icarium's protector.
