The title of this article is a conjecture. Though the topic is found within the RCN series, no official name is given.

A Republic of Cinnabar civil intelligence service headed by Bernis Sand, and of which Adele Mundy is a member.

It apparently has no name other than "Mistress Sand's service",7:2 but has enormous influence. It was also called Cinnabar's civil intelligence service,4:1 but in strictly lower-case and presumably as description rather than name.
