Carmilla
One version of Carmilla was involved with DollarGraveClub, a vampire organisation headed by Varney and also involving Dracula and Lord Ruthven. (PROSE: A Series of Queer Events) Indeed, by one account, she was one of its founders. (PROSE: A Series of Queer Events (2024 reedit)) Her murderous reputation, among others, caused the Interdimensional Pride Council to react negatively when the Man in Grey tried to make DollarGraveClub a sponsor of the Interdimensional Pride Parade in 2022.

The Carmilla of Reality 45 went by the name Carmilla la Fanu, and once owned Castle Erenow in Yorkshire. Concordat agents utilised the tax filings for the property to identify the current owner Lady Erenow, that universe's Jenny Nowhere. Michael Béliveau wondered whether Nowhere had picked up a fondness for anagrams from the vampire. (PROSE: To Hell With Good Intentions.)
