The good, the bad, and the almost irrelevant. They are the miscellaneous characters that are there to answer that one question, explain away that one plot hole, assist in adding development to that actually relevant character, or give that good (or bad) advice. We usually never learn their names. They are there and they are gone as soon as they serve their purpose often never to be seen again. They may not be the most memorable but definitely have a role to play. If the "No Image" picture is used, it means that the particular character has only been mentioned and has never physically appeared.

Flora Sullivan
Flora is from the 1920s and connected to the creation myth of the Vaanti. Despite being in love with Eugene Rosencraft, she is engaged to Arthur Barnaby whom she doesn't love because he threatened her and sent his henchman, Ralston, after her to make sure she doesn't go back on her word.

Eugene Rosencraft

Arthur Barnaby
Arthur is from the 1920s and connected to the creation myth of the Vaanti. He is obsessed with Flora Sullivan and wants to marry her. The marriage is against her will given that Ralston, Arthur's henchman, threatened her at gunpoint and threatened to have Eugene Rosencraft murdered if he didn't stay away from Flora. He shares the same forename as Arthur Vance from It Lives Beneath and Arthur Woods from the Desire & Decorum series.
Ralston
