Wanda seems to be actively spreading this ideology. Because he is attuned to the Arkendish, it is widely believed that Charlie is an adherent of Toolism. While this is not the case, the growing hostility towards Toolism felt by many Royals is already making it much harder for Charlie to persuade them to employ his Archons. This may, in part, be why Wanda is publicizing the ideology.
